Java interface mocking with mocha causes NPE
--------------------------------------------
Key: JRUBY-4356
URL: http://jira.codehaus.org/browse/JRUBY-4356
Project: JRuby
Issue Type: Bug
Components: Java Integration
Affects Versions: JRuby 1.5
Environment: jruby 1.5.0.dev (ruby 1.8.7 patchlevel 174) (2009-12-13
5b119f3) (Java HotSpot(TM) Client VM 1.6.0_16) [i386-java]
Reporter: Hiroshi Nakamura
Attachments: interface_mocking_test.rb
HEAD of JRuby master causes NPE for attached test script.
Followings are my test results for current master (NPE) and 1.4GA (runs without
problem).
Tests for jruby-openssl depends on this behavior.
NB: org.jruby.ext.openssl.impl.Mime is a Java interface.
