What steps will reproduce the problem?

I am not sure that it will reproduce it every time, but it seems to manifest 
when using wsdl2java without any services... at least I see the following 
warning:

... full path to src/main/resources/service.wsdl does not define any services

That is the only clue I have.

What is the expected output? What do you see instead?

I see an error marker in Eclipse telling:

java.util.HashSet cannot be cast to [Ljava.lang.String; 
(org.apache.cxf:cxf-codegen-plugin:2.6.0:wsdl2java:generate-sources:generate-sou
rces)

What version of the product are you using? On what operating system?

Indigo for JEE, 
Windows XP Professional 32-bit.
cxf 2.6.0
latest version of the cxf m2e connector

I am not able to reproduce the same error from a command line build, so I 
suspect that this is maybe an issue with the cxf connector. Also, this 
exception does not turn up in the Eclipse error log file or anywhere else, the 
error marker does not have an exception trace either, so I cannot give a trace 
for this.

I experience this too.

Indigo JEE SR2 on WinXP. I have double checked my codegen plugin configuration 
and everything seems good (and works fine), except this error marker.

After debugging the plugin, I found that cxf 2.6 changed it configuration 
model, causing the type cast.

I have submitted this attach patch.

Please release a new version soon.

Hi,

Just so you know, I tried to revert my CXF version to 2.5.1 to see if the 
problem had been introduced with the new 2.6 configuration model, but I still 
have the error :

java.util.HashSet cannot be cast to [Ljava.lang.String; 
(org.apache.cxf:cxf-codegen-plugin:2.5.1:wsdl2java:generate-sources:generate-sou
rces)

Correct. This is also true for 2.5.1. 

I also confirm that the patch works for cxf 2.5.1.

This consistent with the test pom.xml file in this project that was testing 
with the cxf plugin version 2.5.0.

Patch worked for me. Attaching ready-to-install archive in case someone needs 
it.
Since patch is not applied yet and I had to build plugin archive myself.
For some reason, it took Maven more than hour to download all deps.  Not 100% 
sure that it will suit everyone, since Maven warned about smth environment 
specifics blah-blah. By the way, I applied patch changes manually. I simply 
could not apply HG patch via Hg Workbench, I have never did it before. Total 
noob :). 
Win7 x64, Java 7u4.

Confirming this bug exists with cxf-codegen-plugin 2.7.1
running on Juno SR2, Windows 7 Pro 64-bit.

Also confirming that the archive from Andrii works on this version/platform!
Thank you Andrii and Sebastien.

This got merged last night, after I emailed Ryan asking if he could merge it, 
yay.

Apparently updating the plugin version is tedious, so the update site hasn't 
changed yet, but a step in the right direction!

I've merged the patch and added the updated binaries to the update site.
If anyone has any issues, let me know.
