There seem thread unsafe API in java2d tech. area.

REPRODUCE :
  1) Compile the attached test case(multi.java)
  2) Launch "java multi" in HT machine or SMP machine.
     (Please try to launch several times. )
     You will see the following messages.

[guest@kronos not-thread-safe-java2d]$ java -showversion multi
