[Ikvm-developers] java.lang.IllegalArgumentException: Comparison method violates its general contract!

[Justin S. <jus...@su...>]

I'm seeing an error with IKVM trying to run a swing component.  This issue
does not occur on all of the machines that I test it on, and seems to be
random.  Although, I doubt that is the case.  On my development Windows XP
box (x86) this does not happen, but on a co-worker's box it does.  I can
reproduce this issue either by running the executable, or by invoking ikvm
from the command line from the output jar.  This error does not occur if I
run the class by using the java command.  Again, it does not happen on
every machine that I've tested on.  Any ideas how to track this down?
