Hello, I'm having an issue deploying an EAR file to WebSphere and I think it's related to the JDK.

Running the Jenkins service under the IBM JDK 6 results in a StackOverflowError and crashing of the Jenkins service:

...
Connecting to IBM WebSphere Application Server...
FATAL: null
java.lang.StackOverflowError
at java.lang.ClassLoader.loadClass(ClassLoader.java:668)
...

Running the Jenkins service under:

Oracle JDK 1.8, IBM JDK 1.8, and Oracle JDK 1.6

results in it getting slightly farther, acknowledging the EAR file to deploy and not resulting in a StackOverFlowError: 

...
Connecting to IBM WebSphere Application Server...
The following artifacts will be deployed in this order...

These excerpts are from the Jenkins GUI log. I've attached the console output of these, they have a few more details.

As a note I've changed the projects runtime JDK of both Jenkins to IBM JDK6 and 8, Oracle JDK 6, 7, and 8. It doesn't seem to make a difference.

As I read in the troubleshooting guide Jenkins runs the plugin based off the services JDK, which is what it appears to be doing. However using Oracle and IBM JDK 6 doesn't work either.

Any ideas where I can go from here? Thanks.
