I'm having a problem with the jruby debugger and SWT and Charles Nutter suggested that I open an issue here. The app that I'm trying to debug works fine in non-debug mode or jirb. I'm running on Windows 7 with 64-bit version of Java and JRuby. Here is the output from the session:

C:\Users\Roger\Documents\GitHub\shoes4\lib>jruby --1.9 --debug -r debug
