The java version: 1.7.0-ea-b33 and b99
Platforms: solaris10-x86 and solaris10-amd64
           diadem.sfbay(i586), and sfv20-02.sfbay(amd64)

Problems:
We have printing tests called 2D_PrintingMerlin, when we run the tests on the above platforms and using the above builds, we got core dumped, it is not reproduciable in 1.6.0_10 b29, only in 7.

To reproduce the problem:

1, setenv JAVA_HOME to one of the above builds
2, cd /net/sqenfs-1/export1/comp/2d/tzhang/6ur_2d_ws/2d/src/2D_PrintingMerlin
3, ../../../share/bin/gnumake/solaris-i386/gnumake runauto

You will see core dumped.
