The following JT_JDK/com/sun/jdi test started failing in the 2011.01.13
RT_Baseline nightly:

    com/sun/jdi/BreakpointWithFullGC.sh

Here is a snippet of the hs_err file from a Solaris AMD64 Server
VM -Xmixed config:

#
# A fatal error has been detected by the Java Runtime Environment:
#

So far the above assertion failure has been seen on Linux AMD64 Server-64
VM -Xcomp, Solaris AMD64 Server-64 VM -Xcomp, Linux AMD64 Server-64
VM -Xmixed, and Solaris AMD64 Server-64 VM -Xmixed.


There is a SIGSEGV form of the failure mode. Here is a snippet from
the hs_err file from a Solaris SPARC Client VM -Xmixed:

#

Here is a link to one of the failing configs:

The SIGSEGV failure has been seen in the Solaris SPARC configs.
The 2011.01.13 RT_Baseline nightly had one instance of the
following test fail:

    com/sun/jdi/BreakpointTest.java

Here is a snippet of the crashing thread's stack from the hs_err file:

This failing stack is very similar to the stack in
the BreakpointWithFullGC.sh SIGSEGV failures.


Here is the URL for the failing config:

http://sqeweb.sfbay/net/sqenfs-2/export2/results/vm/gtee/JDK7/NIGHTLY/VM/2011-01-13/RT_Baseline/javase/solaris-sparcv9/server/compd/solaris-sparcv9_javase_server_compd_JT_JDK_com_sun_jdi/analysis.html

Note that in this config both BreakpointWithFullGC.sh and
BreakpointTest.java failed.
