Caveats: This might be an issue with the latest update of the Java 7 JRE instead - it's not clear to me who is at fault. And I know that technically Oracle's JRE for Java 7 no longer supports OS X < 10.7, although there's an easy workaround:

http://stackoverflow.com/q/13536667. So this may only happen with 10.6.8, since I haven't been able to test 10.7+ yet.

Problem: when attempting to test the development appserver with the guestbook demo app as described in the developer guide (

https://developers.google.com/appengine/docs/java/gettingstarted/installing), the appserver fails to launch with the following error messages:

objc[73672]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.7.0_40.jdk/Contents/Home/jre/bin/java and /Library/Java/JavaVirtualMachines/jdk1.7.0_40.jdk/Contents/Home/jre/lib/libinstrument.dylib. One of the two will be used. Which one is undefined.

Versions:
- Java 7 SE, version 1.7.0_40, but NOT present on 1.7.0_25, 1.7.0_17, or 1.7.0_10.
- App Engine SDK version 1.8.5
- Eclipse version 4.3.0 for Mac OS X
- OS X version 10.6.8

Reproducing:
This issue can be reproduced by downloading the Java 7 SE version 1.7.0_25 and 1.7.0_40 JDKs, and following the technique described here (

http://stackoverflow.com/a/13999527) to install both on OS X 10.6.8. With the App Engine SDK installed, try the following command from the developer guide (after cd'ing to the SDK directory):

./appengine-java-sdk/bin/dev_appserver.sh appengine-java-sdk/demos/guestbook/war

Using Java Preferences.app, one can select the 1.7.0_25 JRE and launch the development appserver normally, and then select the 1.7.0_40 JRE and the appserver will fail to launch with the error messages given above.

Huh - that's exactly what my launch configuration looks like (just --port=8888 and a slightly different filepath, but still ending in the "war" folder) and I still get the issue when I change the JRE back to 7u40. What parameters did you have to change?

Thanks a lot! That's just solved

I have the same problem when I updated to 1.7.0_45, and fixed it by rolling back to update 25 (1.7.0_25) on Mac OS X 10.6.8 and App Engine SDK 1.8.6.

This might not be an issue with the appserver, as my colleague was able to run successfully on Mac OS X 10.9.x with JDK 7 update 45 and App Engine SDK 1.8.6.

Might be related to JDK bugs:

Same as lorenzo, I had this error when running the GWT builder on JDK7u45 on OS X 10.6.8. After installing JDK7u25 and using that to run GWT builder instead, the error went away.

Running into this issue on Mac OS X 10.9 with java version "1.7.0_45"
