Java plugin with stack overflow error after upgrading to Sonarqube 5.6.4 and Java plugin 4.4.0.8066

[Bernd G.]

I'm running into a stack overflow error during a sonar scanner analysis for a project that worked fine with Sonarqube version 5.1.2 and Java plugin version 3.5. I'm obviously trying to uprade to the latest versions, which are Sonarqube 5.6.4 and Java plugin 4.4.0.8066.

I can't disclose the source code that triggers the stack overflow. I will try to run a unit test with that source code in the Java plugin by cloning the project, but I currently fail with build issues. The usual stuff - stacking up one problem on top of the previous one, I hope I don't run into a stack overflow myself ;-) - anyway, that's another story and i will create aseparate message/issue for that.

But maybe somebody out there has seen this one already. Here's the exception stack trace:
