You really ought to be using JRuby 1.1.x...1.0.3 is the last maintenance 
release to 1.0 and that line has not seen any updates in over a year. 
1.1 just had a 1.1.3 release that's worlds better as far as 
compatibility and far faster. If this bug still exists in JRuby 1.1.3, 
please file an issue for it :)
