The swat tests(Java2Demo and SwingSet2) crashed in solaris 10 s10x_u7wos_08 or solaris 11 snv_146 amd64 with jdk 1.7.0-ea-b110 swat build, please see attached core dump file.

The SWAT test is to launch the two tests with auto run option and with vm flags,
in jdk 1.7.0-ea-b110 swat build, these two tests crashed, but other platforms are running fine. You can take a look the swat test result page at:
http://sqeweb.sfbay.sun.com/nfs/results/vm/gtee/JDK6UR/SWAT/VM/6-swat/2010-09-16_02/
click red 2 in VM solaris-amd64-only, you will see the the two tests are failed with core dump.

How to reproduce the problem:
use jdk1.7.0-ea-b110 to launch the tests with -d64 -client -Xint or -d64 -client -Xmixed or -d64 -server -Xint or -d64 -server -Xmixed
and options: -runs=1 -delay=3 -antialias=true -rendering=true -verbose -ccthread -zoom
