When running java_g with -XX:+CompileTheWorld, the sun/java2d/SurfaceData class gets
compiled and it's static initializer is being called. If DISPLAY is set to nothing,
then the initializer calls the DGA library with empty DISPLAY and fails with a core dump.
If DISPLAY is set to something, this doesn't happen. Looks like a bug in the DGA
library, but I guess it could be worked around by checking the DISPLAY variable for a
non empty value before calling the DGA code. Please advice. Otherwise, -XX:+CompileTheWorld
doesn't work. Please see the stack trace and original description from HP below.

Bug Workaround: Setting the DISPLAY variable prevents the SIGSEGV.
