JRuby 1.4 - jruby -S rake manifest results in empty manifest file

[awksedgreep]

It appears to execute normally, but the file is empty.

Here's JRuby:
mark-cotners-macbook-pro:SNMP4JR markcotner$ jruby -S rake manifest
(in /Users/markcotner/ruby/gems/SNMP4JR)

This particular library only needs JRuby to run, not install. Currently I'm just building the gems with MRI and installing them with JRuby, but I thought you all would like to know about the potential bug.
