Title: Error: Exception in thread "main" java.lang.StackOverflowError

This is caused by the JVM. The JVM can only handle calling about 75 methods deep (ie. methods called from other methods) per thread. This is becoming a seious issue with all of these frameworks building on top of each other. If you look through the stack trace, you can see that it takes 5 invoke methods before a Web Service client actually gets near the service. Then you have the commons.discovery package also using 11 methods just to find an object.

The solution is to spawn another thread at some point and keep going through your method invokations from there. However, in this situation that may not be feasible. The only thing I can think of is if your services or handlers can use a thread to do their work (you would have to make the normal main thread wait for that thread), I know it seems like a waste, but is becomes necessary until they alter the JVM to allow you to specify the stack size. You could look into alternative implementations of the JVM to see if others allow you to do this.
