sbt crashes on build when using OpenJDK

[candera]

When attempting to compile cccp via sbt, I get the following error:

This doesn't repro when using the Sun JDK:

sudo update-java-alternatives -s java-6-sun
sbt stage

Works fine.

Given that this is apparently an issue with the IcedTea VM, I'm going to close this. I'm not sure there's anything I can do about the Scala compiler triggering a segfault. :-)

Fair enough.
