Call to Ruby class implementing a Java interface fails with
IllegalMonitorStateException
----------------------------------------------------------------------------------------
Key: JRUBY-3100
URL: http://jira.codehaus.org/browse/JRUBY-3100
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.1.4
Environment: Fedora Linux 9, Sun Java 1.6.0_10, JRuby 1.1.4 or JRuby
trunk, Eclipse RCP 3.4 or 3.4.1
Reporter: Uwe Kubosch
Priority: Critical
I have a ruby class (FlightsEditorContentProvider) implementing a Java
interface (IStructuredContentProvider), and an interface method (inputChanged)
on the Ruby class is called from a Java class (ContentViewer).
ON JRuby 1.1.3 it works fine, but on JRuby 1.1.4 and trunk (2008-10-30) it
fails with the following stack trace. Using the Eclipse debugger and stepping
INTO the call to inputChanged() skips a stack frame in the generated
InterfaceImplXXX object, and shows a call to
JRubyClassLoader(ClassLoader).loadClassInternal(String) line: 320
with the argument "org.jruby.java.MiniJava"
This has stopped our project in its tracks, so I hope you can look at it
quickly. I'll get right onto trying to make a minimal example, but since the
code is run inside the Eclipse RCP framework, "minimal" may still be large.
Maybe you can look at it in the meantime?
