Frame in ThreadContext's frameStack holds reference to unreachable RubyObject
-----------------------------------------------------------------------------
Key: JRUBY-2712
URL: http://jira.codehaus.org/browse/JRUBY-2712
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.1.3
Environment: Mac OS X 10.5.3; J2SE 5.0
Reporter: Micah Alles
Attachments:
test_thread_context_frame_dereferences_unreachable_variables.rb
In some cases references to unreachable local variables in methods are not
collected due to a Frame object in the jruby runtime which is referencing it
via its {{self}} instance variable. The cause of the leak was observed by
inspecting a memory snapshot of the jruby process which was taken after pausing
execution before the assertion in the included unit test with a call to
{{sleep}}.
The included test fails on trunk (r7037) and passes against the 1.1.2 branch.
