Forum: JRuby Mysterious JRuby stack trace

Hi guys,


I'm using JRuby 1.4.0 complete jar in one of my projects. I'm executing 
it from ant via the exec task:
java -jar jruby1.4.0.jar script.rb script_params

The thing is, on some computers I receive this:
[exec] Exception in thread "main" :1: no !/ in spec (IOError)
[exec]    ...internal jruby stack elided...
[exec]    from (unknown).(unknown)(:1)

Has anyone encountered it before? What can I do to get a more 
informative stack trace?

Hi George,

Anything particularly interesting in script.rb?
Do you see the same even with simplest script.rb?

Also try to use -b command line switch, anything more interesting 
printed?

java -jar jruby1.4.0.jar -b script.rb

Thanks,
  --Vladimir

Any suggestion would be helpful. Is there any switch I could pass to 
JRuby and see a full stack trace?
