      A DESCRIPTION OF THE REGRESSION :
      -------------------------------

      Applet crashed in Mustang if using an image for double buffering, and drawRect starting from [0,0]. The problem is reproducible in Mustang b72/73 either using the browser to load the applet or run the applet frame direcly as a standalone program.

      The same test case works fine using 5.0_u6 release. It's a regression.
      The test case is only a demonstration, the same problem seems to cause
      frequent crashes in some other AWT operations
       * like Window handling etc.
       * Java crashes in browser using applet or directly using java.exe


      REPRODUCIBLE TESTCASE OR STEPS TO REPRODUCE:
      -------------------------------------------
      Compile and run the attached test case <AppletFrame.java> as a standalone program or open the applet using IE/NS/FF browser.



      RELEASE LAST WORKED:
      5.0 Update 6

      RELEASE TEST FAILS:
      mustang-beta/b72/b73

      Tested on: solaris-sparc9(gnome2)/XP-pro

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      The applet should open a frame.

      ACTUAL -
      The frame shows up for a moment and then the browser crashes with the following error pid:

      solaris-sparc-standalone
      ------------------------

      See attached <hs_err_pid6872_solaris.log>
       




      Windows-XP/browser
      ------------------

      See attached <hs_err_pid2724_windows_browser.log>


      APPLICATION NAME: e-health.solutions Electronic Health Record by GMD APPLICATION VERSION: 3.6

      OBSERVED APPLICATION IMPACT:
      The crash of the complete browser is critical problem making Mustang unusable for many applets.
      The problem seems not only to show up in the given testcase but also on several awt operations.

      Release Regression From : It works with 5.0u6 but fails with Mustang

      Release Regression From : mustang
      The above release value was the last known release where this
      bug was known to work. Since then there has been a regression.
