Setup: a cygwin X server running on WinXP, from this machine 'ssh -X you@linux'
to a linux machine, and display SwingSet2 (the one with the new splash screen).
(I could not reproduce this when displaying from a solaris-sparc system,
but the splash screen was not rendered correctly - the transparent
parts were rendered black, same as with linux)

In jdk6, it crashes:
Stack: [0x404d4000,0x406d3000), sp=0x406d2a1c, free space=2042k
Native frames: (J=compiled Java code, j=interpreted, Vv=VM code, C=native code)

(hs log file attached)

It doesn't crash on jdk7 presumably because of a known
exception which happens earlier:
