Issue Type: Bug Bug
Affects Versions: JRuby 1.7.0.RC1
Assignee: Unassigned
Components: Java Integration
Created: 27/Sep/12 12:17 AM
Description:

Please see:

https://github.com/dekellum/ji-tests/blob/maste/test/test_exception_runner.rb

All tests pass on jruby 1.6.8. On jruby 1.7.0.RC1 the following, somewhat bizarre failure occurs for the last test:

  1) Error:
test_raise_threaded(TestExceptionRunner):

If the test is changes to allow the "exception" to be raised out of the test, then the even stranger error:





NoMethodError: undefined method `backTrace' for nil:NilClass






occurs instead.
