When the java platform gem does not get release it breaks any users that want to install latest io-wait gem on JRuby, and prevents upgrading JRuby's default gem. It appears this has happened again with 0.3.2 and 0.3.3.
I would request that the -java versions of these gems be released, or alternatively give me push access and I will release them.
We need to cooperate to make sure every release includes both the C extension gem and the JRuby extension gem. Please let me know how I can help make this easier.
