URL: http://jira.codehaus.org/browse/JRUBY-1293
Project: JRuby
Issue Type: Bug

This is happening in the maven-based build, but not the ant build for some
reason, in the {{test_higher_javasupport}} test.

If I turn off JIT by passing {{-Djruby.jit.enabled=false}} to the process
running the test, the failure no longer occurs.
Because of this, I'm turning off JIT in the maven build until this issue is
resolved, to allow the automated builds to succeed.
