Method caches are hard references, could keep methods and their associated
modules/classes alive
------------------------------------------------------------------------------------------------
Key: JRUBY-3087
URL: http://jira.codehaus.org/browse/JRUBY-3087
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Reporter: Charles Oliver Nutter
Fix For: JRuby 1.1.6
In 1.1.5 we moved method caching to a passive flushing system. All our method
caches also contain hard references to method objects. This means that a cache
site could hold a method indefinitely after it has been replaced if the cache
site is never activated again. We need to analyze the likelihood of this
happening, determine the potential impact, and consider using weak references
for all method caches.
