java.awt.Component.instance_of?() expects 2 args
------------------------------------------------
Key: JRUBY-5132
URL: http://jira.codehaus.org/browse/JRUBY-5132
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules, Java Integration
Affects Versions: JRuby 1.5.3
Environment: WinXP SP2, Java 1.6.0_20-b02
Reporter: Bill Dortch
Calls to instance_of?(aClass) on java.awt.Component (class, not instances) and
any subclasses (including javax.swing.JComponent and subclasses) results in an
argument error. I've dumped the stack at the point the RaiseException is
created:
{noformat}
>jruby -e "require 'java'; puts java.awt.Container.instance_of?(Class)"

Also, it's looking for method isInstanceOf. Definitely a weird one.
