Debugging jrubyc

Hey all,

I am exploring using jruby with Apache Jackrabbit. I have been able to
convert and run the examples from this page in jruby:

http://jackrabbit.apache.org/doc/firststeps.html

~/workspace/jr $ jruby first_hop.rb
Logged in as anonymous to a Jackrabbit repository.

My next step was to try to use the jruby compiler (using jruby from the
trunk) to see if that would give a performance increase, but upon
executing
I get an exception:

~/workspace/jr $ jrubyc first_hop.rb
Compiling file “first_hop.rb” as class “first_hop”
~/workspace/jr $ java first_hop
Exception in thread “main” java.lang.ArrayIndexOutOfBoundsException: 0
at first_hop.file(first_hop.rb:24)
at first_hop.run(first_hop.rb)
at first_hop.main(first_hop.rb)

I’m not sure how to debug this…line 24 in the first_hop.rb is when I
create a new ‘TransientRepository’…full code of the first_hop.rb is
below…any suggestions / comments?

Thanks,

Dylan
