      Description

      I try to automate my tests by running them with DISPLAY set to an
      Xvfb server I maintain. If I run the "java2demo" basic acceptance test
      like this:

      /java/jdk/bin/jdkx2 -b /some/jdk java2demo

      then it intermittently fails (20% of the time?) when DISPLAY is
      an Xvfb server.

      To reproduce, log onto "suttles.sfbay" and set DISPLAY=lasker:7

      Then

      repeat 5 DISPLAY=lasker:7 /java/jdk/bin/jdkx2 -b ~/ws/mustang/build/solaris-sparc java2demo

      eventually gives:

      cd /u/martin/ws/mustang/build/solaris-sparc/demo/jfc/Java2D
      /u/martin/ws/mustang/build/solaris-sparc/bin/java -jar Java2Demo.jar -runs=1 -delay=5 -ccthread

      Java2D Demo RunWindow : 1 Runs, 5 second delay between tabs
      java version: 1.6.0-internal
      SunOS 5.9
