When I switched to the `nouveau' display driver, thus enabling glx,
NetBeans was able to launch successfully.

Given that NetBeans was failing during the 'enabling modules' stage, I'd
say it was crashing when it tried to launch a module that used GL
visualization features.

Looks like openjdk needs more tests run on displays lacking glx
extensions.

Title:
  NetBeans 7 crashes OpenJDK with SIGSEGV in glXChooseVisual when GLX
  not available on display

Status in “openjdk-6” package in Ubuntu:
  New

Bug description:
  Launching NetBeans7 RC1 from http://netbeans.org/ fails with a SIGSEGV
  on a freshly installed Ubuntu 11.04 system with OpenJDK 1.6.0_22. The
  segfault is in libGL.so.1 at glXChooseVisual+0x106eb .

  Running "glxinfo" reports:

  Xlib:  extension "GLX" missing on display ":0.0".
  Error: couldn't find RGB GLX visual or fbconfig

  ... so I suspect the issue is that OpenJDK isn't coping cleanly when
  GLX isn't available.

  It appears that the JDK has been restructured to try to merge the
  -headless and regular jdks, given that `dpkg -S
  /usr/lib/jvm/java-6-openjdk/bin/java' reports `openjdk-6-jre-
  headless'. Attempting to 'apt-get --purge remove openjdk-6-jre-
  headless' shows that openjdk-6-jre now depends on openjdk-6-jre-
  headless. This may be related to the problem.
