SwingSet2 is crashed by running it in Solaris_amd64 machine using jdk1.7.0-b107 swat build. It is running fine with in solaris-i586, solaris-sparc and windows.
Please see below core dump summary and a core dump file as attached.

Test log can be found:

It can be reproducible by running it java -jar with following flags:
-d64 -server -Xmixed; or -d64 -client -Xint; -d64 -server -Xint; -d64 -client -Xmixed

SUGGESTED FIX http://sa.sfbay.sun.com/projects/java2d_data/7/6980281

EVALUATION This crash happens in optimized code which is produced by ss12u1 compiler. Note that same problem for ss12 was workarounded by disabling optimization if compiler version is greater than 5.8. However, version check, introduced in fix for 6729772, does not work correctly for ss12u1 (version 5.10). This fix just modifies the version check to use major and minor compiler versions to make a conclusion whether optimization disabling is required.

EVALUATION There are two similar CRs in jdk7 EC list: 6980281 and 6984956. They report a crash in ductus engine on solaris-x64 (64bit mode only). I have reproduced this problem, and found that this crash is likely caused by a problem in optimized code, generated by SS12u1 compiler. It can indirectly confirmed by following facts: * problem is not reproducible if compiler from SS12 is used. * problem is not reproducible on debug and fastdebug builds even if compiler from SS12u1 is used. * problem disappears if debug printing is added to ductus code. However, our promoted builds are created by using SS12u1 (at least, same testcase causes a crash in b115 ), so we need to workaround this problem on jdk side.

EVALUATION b107 was accidently built with the wrong compilers on Solaris (SS12u1), they are rebuilding b107, this should be tried again after RE re-builds b107 with SS12.

EVALUATION The stack trace suggests the problem on the 2D side sun.java2d.pipe.AAShapePipe.renderPath(Lsun/java2d/SunGraphics2D;Ljava/awt/Shape;Ljava/awt/BasicStroke;)V+308
