P2
This failure showed up on a new jtreg test that tests forceEarlyReturn in JDI.
The test is EarlyTest.java (in my workspace).
I put some printfs in and got a similar failure here at this line in
JvmtiEnvBase::check_top_frame (jvmtiEnvBase.cpp)
symbolHandle signature(java_thread, jvf->method()->signature());
I think the problem is that the back-end is calling JVMTI ForceEarlyReturn
on something other than the 'current thread'.

I put some printfs in and got a similar failure here at this line in
