I've upgraded from jruby 1.7.16 to 1.7.17 today and ran into a NPE which seems to be regression in the latest release.

Example:

|jruby-1.7.17@debug_issue| thq-m-dkoeh01 in ~/workspace/debug_issue_with_jruby_1_7_17
 ±  |master ✓| → rspec test.rb --debug

 /Users/dkoehler/.rvm/gems/jruby-1.7.17@debug_issue/gems/ruby-debug-base-0.10.4-java/lib/ruby-debug-base.rb:214 warning: tracing (e.g. set_trace_func) will not capture all events without --debug flag

To reproduce this error, I've create a minimal project:https://github.com/phrinx/debug_issue_jruby_1_7_17.

It seems the culprit here is 'simplecov' commenting out the block at https://github.com/phrinx/debug_issue_jruby_1_7_17/blob/master/spec/spec_helper.rb#L3 does not reproduce the error.

We would like to release 1.7.18 very soon, so let us know if @mkristian can't get to it.
