i just checkout out the latest 0.9

no matter what java options i use in sbt/sbt (i tried -Xmx6G -XX:MaxPermSize=2000m -XX:ReservedCodeCacheSize=300m) i keep getting errors "java.lang.OutOfMemoryError: PermGen space" when running the tests.

curiously i managed to run the tests with the default dependencies, but with cdh4.5.0 mr1 dependencies i always hit the dreaded Permgen space issue.

Any suggestions?
