jirb_swing crashes in interface.rb
----------------------------------
Key: JRUBY-1545
URL: http://jira.codehaus.org/browse/JRUBY-1545
Project: JRuby
Issue Type: Bug
Components: Java Integration
Affects Versions: JRuby 1.1b1
Environment: Windows XP Pro SP2, Sun JDK 1.6.0_03-b05, JRuby 1.1b1
(binary)
Reporter: Henrik Mohr
This can be reproduced:
Command prompt: jirb_swing
Inside jirb I type the following (note the "=> false" from the require 'java'!):
irb(main):001:0> require 'java'
=> false
irb(main):002:0> class MouseL < java::awt::event::MouseListener
irb(main):003:1> def mouseReleased
irb(main):004:2> p "mouse released"
irb(main):005:2> end
irb(main):006:1> def mouseClicked
irb(main):007:2> p "mouse clicked"
irb(main):008:2> end
irb(main):009:1> end
This makes jirb_swing hang completely, and throw the following exception in the
command line:
