Target platform: Solaris 11 Sparc Ultra 60
Build: J2SE 6.0 build 49

Problem:
This is not a regression. It reproduces from Mustang build 47 to 49 on Solaris 11 Sparc b21.

Step to reproduce:
1) Install JDK 6.0 build 49 (tar.Z) onto the test system
2) cd <installed_JDK-b49_dir>/demo/plugin/jfc/Java2D/
3) Execute <installed_JDK-b49_dir>/bin/appletviewer Java2Demo.html

Expected result:
It should not have an exception. Java2Demo GUI should change the states.

Actual result:
java.lang.ArrayIndexOutOfBoundsException
