I am sure this is a minor bug: It seems as if jruby get's the currently executed line wrong. Take this example file:

puts "hello"
require 'pry'
binding.pry

Now with the pry gem installed in both jruby and mri:

$ ruby --version
jruby 1.7.3 (1.9.3p385) 2013-02-21 dac429b on Java HotSpot(TM) 64-Bit Server VM 1.7.0_10-ea-b14 [darwin-x86_64]

$ ruby hello.rb
hello

From: /Users/robin/hello.rb @ line 1 :

 => 1: puts "hello"
    2: require 'pry'
    3: binding.pry

[1] pry(main)> exit

~
$ rbenv use 1.9.3

~
$ ruby --version
ruby 1.9.3p392 (2013-02-22 revision 39386) [x86_64-darwin12.2.1]

~
$ ruby hello.rb
hello

From: /Users/robin/hello.rb @ line 3 :

    1: puts "hello"
    2: require 'pry'
 => 3: binding.pry

[1] pry(main)>

You see how in jruby pry thinks it's still in the first line, though it must be in the third line or the repl wouldn't have kicked in?

I'm unfamiliar with how pry works. Have you asked them what might be causing this? It would help us if we can reduce the problem a little further with their help.

This works by running jruby in debug mode (e.g. export JRUBY_OPTS=--debug) and is fixed in master altogether.

I just tried the example snippet on 1.7 and 9k branch and both show the proper line. Closing. Not sure when it was fixed and not worth the time to isolate when for posterity.
