Hello,

Currently we are using 1.5.3 version, I thought of verifying the build with latest 1.6.2 RC mainly for its compiler changes.

Our application supports All browsers, when i try to compile without restricting user.agent it fails and gives below exception. But, if i restrict my user.agent to ie6 alone its working fine.

 [java]    [ERROR] Unexpected internal compiler error

@Scott: does this look like something you might have seen before?

@karthikeyan + dapeng: Do you know if the compilation error occurs when restricting the user agent to another other singular browser target? Or does it only occur when a specific user-agent isn't specified for compilation?

Thanks for the reply Scott. I generally do my compilation without specifying user-agent, since i got this message I was trying out some options considering it could be memory issue, one of the thing i tried is setting user.agent to be ie6 alone, and it worked without this compilation error.

In gwt 1.5.3 all works without specifying user.agent property too.

I tried passing firefox target alone it failed. But havent tried with safari or opera options.

This is a plain old Java stack overflow... in 1.6 we serialize/deserialize large object graphs which takes more stack than was needed in GWT 1.5.

If your project is failing, try using the "-Xss" JVM option to give the compiler more stack size.

Thanks Scott, adding Xss has fixed it.

@dapeng: you're likely facing the same problem. Please give Scott's suggestion a try to see if it resolves the issue.

Marking issue as Invalid.

Actually, I would like to make AST serialization take less stack, so let's leave this open.

GWT version: 1.6.3 Helped only on one computer, with java 1.6 installed(Windows). If I try to compile with java 1.5.0_09(Windows) on other computer it fails StackOverflowError even if I set -Xss100M, if I set more than 120Mb it throws OutOfMemoryException.

Also I've tried to compile with java 1.5.0_16 on other(third) computer(Centos4.4) and compilation succeded.

Any ideas what can be wrong with java 1.5.0_9+GWT1.6.3+WindowsXP?

I have the same issue, our project compiles on gwt 1.5.3 but on gwt 1.6.3 throws unexpected compiler exception, we tried with Xss but nothing.

same issue whith gwt 1.6.x. Problem seems to come from firefox compilation... If i restrict user.agent to firefox, i get compiler exception; even if i increase Xss. Restricting user.agent to ie6 works fine.

I am having this problem in 1.6.4, on a project that compiles correctly under 1.5.2.

The stack trace consists mostly of repetitions of: at java.io.ObjectOutputStream.defaultWriteFields(Unknown Source) at java.io.ObjectOutputStream.writeSerialData(Unknown Source) at java.io.ObjectOutputStream.writeOrdinaryObject(Unknown Source) at java.io.ObjectOutputStream.writeObject0(Unknown Source)

It also has sections like:

at java.util.ArrayList.writeObject(Unknown Source)
at sun.reflect.GeneratedMethodAccessor44.invoke(Unknown Source)
at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source)

at java.io.ObjectOutputStream.writeSerialData(Unknown Source)
at java.io.ObjectOutputStream.writeOrdinaryObject(Unknown Source)
at java.io.ObjectOutputStream.writeObject0(Unknown Source)

It does not seem to matter if I target a specific browser.

The error message with the complete stack trace is attached.

The argument to -Xss is actually a stack size. You can set it even larger than 1024k. If -Xss1024k gets stack overflows, please try with 2048k or 4000k.

Increasing the stack size fixed the problem for me, though I appreciate ScottB's desire to make the process use less stack.

Also, I somehow missed ScottB's very relevant comment #4 when reading this issue the first time. It might be useful to be able to tag comments as "workaround/solution" to make them stand out.

Maybe changing the subject will help a bit.

No luck.

I've tried up to 50M Xss. Above that, I run into OutOfMemoryError's.

If I build with 1 permutation (FF only), it completes successfully. If I run against all 5 permutations, I get a StackOverFlow error always. I have not tried targeting other permutations specifically.

My compile command: java -Xss50M -Xmx1000M -Xms64M -cp %CLASSPATH% com.google.gwt.dev.Compiler -war %OUT_DIR%

I got 1.6.4, it still no luck. tried Xss to 56M, still get java.lang.StackOverflowError

I have a fix for this. I'd like to actually roll it into any potential 1.6 updates we do, so it's against 1.6. It would probably require some manual massaging to port to trunk from here.

Follow-up to my previous comment #15:

I managed to get it to compile. Turns out, my compilation script was defaulting to JDK 1.5. By switching my PATH to use JDK 1.6.0_10, I'm able to compile.

What I've noticed: - On our 64bit Win2k3 system w/ JDK 1.5.x, even -Xss50M is not sufficient - On our 64bit Win2k3 system w/ JDK 1.6.0_10, the only parameter I need is: -Xmx1200M - On our 32bit WinXp & Vista systems, we need to specify -Xss32M. Not sure if 32M is really needed, but it worked.

Summary: Make sure you're on JDK 1.6

I had this problem and was already using Java 6.0

I followed the suggestion above to add

and I can compile successfully with Ant now. But the Eclipse plugin for compiling and the compile button the hosted mode server both get stack overflows.

Issue 2794 has been merged into this issue.

Anyone want to try this patch jar and see if it both fixes your issue and compiles successfully? Ideally, you could remove the -Xss spec and still get a clean compile.
Just place this jar in your classpath higher than gwt-dev-.jar.

Note that this will only likely work with GWT 1.6.4.

I'm trying to migrate my project from GWT 1.5.3 to GWT 1.6.4:

OS: Windows XP, 32 bit GWT: 1.6.4 (svn revision 1.6@5189) Java: java version "1.6.0_13" JVM Args: -Xms512M -Xmx1024M

I'm using Maven2 with com.totsp.gwt:maven-googlewebtoolkit2-plugin for building. This plugin loads GWT compiler directly from GWT home directory, so gwt-dev-patch JAR file had to be merged into gwt-dev-windows JAR file (instead of simply prepending it to the dependencies list).

Before gwt-dev-patch: 2 modules out of 3 failed with StackOverflowError, even when the extra JVM arg -Xss64M was set After gwt-dev-patch: 3 modules out of 3 succeeded. No need for the extra JVM arg -Xss.

That's terrific news.

It should also compile faster too, no?

Scottb, I had the same problem and the patch has worked really good for me! Thank you!

i did update our app from 1.3 to 1.5 and 1.6.. on JDK5 and JDK6 got java.lang.StackOverflowError and also outOfMemory errors...but with patch compiles OK, even without Xss flag! my build settings:

            <jvmarg value="-Xmx512M"/>              
            <jvmarg value="-Xms256m"/>              
        </java>

have to admit it was a large app and in 1.3.3 style, so many raw types

@Scott, the patch LGTM.

Thanks, Bob. Committed to 1.6 branch @r5262.

Issue 3585 has been merged into this issue.

Wonderfull

Congratulations from Brazil to Scott! (post 21)

Is there a scheduled release for this?

Great.

Congratulations from Chile to Scott! (post 21)

just want to add that the patch by scott worked for me too, thx!

@scottb

Hi, Scott,

I read the topic about the stack overflow and I tried your solution, but I had no success on it. Could you help me?

I downloaded "gwt-dev-patch", and add to and then I opened -> properties -> Libraries -> Add JARs and added the jar you made.

My .classpath got this extra line:

After that, I ran the project and clicked on Compile/Browser... I got a message: "GWT module 'index' needs to be (re)compiled, please run a compile or use the Compile/Browse button in hosted mode"

At Google Hosted Mode, the error: " [ERROR] Unexpected internal compiler error java.lang.StackOverflowError: null at java.io.ObjectStreamClass.lookup(ObjectStreamClass.java:244) at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1029) at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1369) at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:1341) [...] "

It is the same error, you, guys, discussed on this topic. I wasn't able to use -Xss, I think it is due to my application, it is too large.

If you have any ideas....

Thanks Eduardo

@scott

Just adding...

I tried to remove gwt-dev-windows for my gwt libs and I couldn't manage the project 'cause of other libs on gwt-dev-windows original.

Then I opened the original one and add the code which you wrote into the original one, and I couldn't compile it.

Well, this is it.

Thanks

Edaurdo: don't but the patch jar in WEB-INF/lib, put it somewhere else, like your GWT install directory. Also, you need to make sure on the classpath that the patch jar comes JUST BEFORE gwt-dev-windows. So it should look like this in your .classpath file:

@scott

Sorry for all this posts! I put it to work!

Thanks

humm

I will try this one. 'Cause I put the gw-dev-patch content into gwt-dev-windows. It gave me a little work, but I got it working. ^^

Thanks a lot

thanks scottb. it works!

Great! Thanks scott. it works.

Thanks a lot, it works perfectly

Hey its working fine.. I was having the same problem and now it has been solved by using the patch. I am working on a GWT GXT application using eclipse plug-inns. After adding the gwt-dev-patch.jar file with my GWT library files everything works fine. In eclipse at Window -> Preferences -> Java -> Build Path -> User Libraries -> I added the Patch to my GWT library and also moved the position of gwt-dev-patch.jar just above gwt-dev-windows.jar. Now when I clicked the Compile Button I get: Compiling module XXXXX Compiling 5 permutations Permutation compile succeeded Linking into war Link succeeded Compilation succeeded -- 43.813s

Cheers..!!

Thanks Scott.

Thanks, works for me too.

I am using maven plugin com.totsp.gwt.maven-googlewebtoolkit2-plugin and had to merge the patch jar with my gwt-dev-windows.jar but can now build from command line (mvn gwt:compile) or using the compile button in hosted mode browser. Thanks, again.

Patch solved problem here too. Thanks.

Awesome ! We were desesperate by this stack overflow exception and the patch solved our problem. Best regards.

It also works for me, thank you.

works for me, I use maven with com.totsp.gwt.maven-googlewebtoolkit2-plugin, make sure the patch on top of other classpath.

Hi, I try all you suggestions for risolve the same problem but without results. I follow Comment 46: - download patch - In inside the path gwt-windows-1.6.4 I added the gwt-dev-patch.jar - In eclipse : Window -> Preferences -> Java -> Build Path -> User Libraries -> created a new User Libray with inside all library of GWT and the patch. - Added the user library betwean the library of the project - Click button GWT Compile Project

The error still to be

Really thanks for this patch. This have solved compiling issues on my very first real appplication. I'm using GWT 1.6.4 + GXT 2.0 M3 + GWT-XMLRPC + GWT-LOG Could we have more information about this patch and when it should be integrated in official release ?

Scott you are the BEST!!!!!!!!!!!!!!!!

Thanks guys, I'm going to lock this issue down now to make it easier for people to find what's important.

Options for getting this fix: 1) See comment #21 for a jar you can use with GWT 1.6.4. 2) Build GWT's releases/1.6 branch yourself from source. 3) Wait for GWT 1.6.5 to be released.

This shipped in GWT 1.7.0.
