[Jikesrvm-core] NullPointerException in VM_CollectorThread: A plea to compiler and GC gurus.

[Steven A. <au...@wa...>]

The most serious repeated bug is that the nightly regression
tests on Linux/x86 often come back with at least one instance
of defect # 4126, NullPointerException in VM_CollectorThread.

The following messages on jikesrvm-regression describe the problem:

I would really like to see this bug caught before our release goes out 
on Monday.  The two candidates, to my mind, are a code generation bug 
in the opt compiler or a bug in the GenMS garbage collector.

If anybody can take a look at this and try to track it down, it would
mean that we release 2.3.4 as a more robust system.
