[Bio-Linux] Tablet and x2go crashes the current session

[Tim Booth]

Hi Sej,

OK, I can only vouch for the bio-linux-tablet version running on the
default OpenJava JVM as that's the only one I test.

If there is some feature you need in the new Tablet version then let me
know and I'll try to prioritise updating it.

The issue is probably not with tablet or Java per-se but with the
graphics libraries they use.  The libraries on Ubuntu have been patched
to fix these issues and make them x2go compatible, and the DEB packages
are then compiled to use the system libraries, which is why the official
packages generally work.  If you install Java or Tablet manually you'll
find they come bundled with their own un-patched graphics libraries.

Cheers,

TIM
