Can a full codecache trigger CMS?

[Bernd Eckenfels]

I read that in the event of Code cache Sweep or Full it may Trigger a FullGC(which makes sense to get rid of unused classes).

Since I run with ExiciyeGCInvokesConcurrent - it can lead to CMS over this road?

We really need GCCause Reasons in gclog and a better event diagnostics.

(one thing I appreciate at IBM jre is the clean GC log and the trace buffers)
