The exit status of 1 indicates an ungraceful termination due
to an out of memory condition. My search showed failures
like this on Solaris X86, Solaris AMD64, and Solaris SPARC

Fix pushed. I will close this bug when test is stable in nightly. http://vmsqe-app.ru.oracle.com/hg/sqe/vm/9/ws_int_spb/vm/rev/0c4833fee30c

The debugger will allocate memory in the debuggee until it gets a VMOutOfMemoryError. The purpose of this is just to verify that VMOutOfMemoryErrors are generated. But since we allocate memory in the debuggee until it gets an OOM, we sometimes also get an OutOfMemoryError in the debuggee. The default debuggee considers this as an error and the test fails. Proposed fix is just to ignore any OOM in the debuggee, since they are quite expected.

I can not reproduce this with parallel GC, but with G1GC it failes every time.
