[macosx] in closed/java/awt/Component/6307563/bug6307563.java, empty buffer strategy

      Description

      As suggested in 7124552, I'm filing a separate bug about closed/java/awt/Component/6307563/bug6307563.java regression.
      Here in onEDT20(), window.getBufferStrategy() is null.
      Should it be not null at this moment?

      java.lang.NullPointerException

      After a reboot of my Windows XP SP3 OS laptop, I was trying to run bugster 2.21.0.02[Production], the interface froze on me after entering the bug number to display. I "end process" the javaw process, then ran it again. Same symptom. A third time and it ran as expected. I did not cdo any clearing of caches or deleting the local Application Data/Sun/Java directories Sorry I don't have any further details.

      ###@###.### suggested this bug as the possible culprit if it involved BufferStragegy, and asked if I saw it again, to include the details here. The full trace disappeared off the filesystem, but at least I have the stacktrace (below).
