Local fix

Problem summary

• Root cause of the problem was that Color management module uses
  multiple worker threads to process a color conversion routine in
  parallel mode. It uses joinable  threads and pthread_join () to
  synchronize main processing thread with worker threads.
  Sometimes pthread_join() fails to synchronize threads under high
  load ,which can lead to crash in following routines -
  - pthread_join()
  - evalTh1i3o3d8()
  This problem also reported in  Oracle bug id 6935062.
  

Problem conclusion

• This defect will be fixed in:
  5.0.0 SR14
  6.0.0 SR16
  6.0.1 SR8
  .
  JVM is fixed  by using detached worker threads and semaphores in
  Color management module's internal multi-threaded subsystems.
  

Temporary fix
