My Java 7 JVM is crashing in a Stack Overflow (which is a Bug initself). But while inspecting the hs_err file (attached) I noticed that the OSGi Parser has a extremly deep stack. I wonder if this is a endless loop bug or if it is caused by the many OSGi modules I have deployed in this 7.1.1.final AS7.

I am not entirely shure what triggered the problem, at is happening after startup. But I think it was related with clicking the OSGi Runtime Management in the JBoss Managagement Console. There are roughly 250 bundles in the deployment list of the server group.
