It supports bits of it:

http://builder.classpath.org/japi/openjdk6-libgcj.html

And yes, there are known holes in java.net and ResourceBundle.  I've
looked at implementing them a couple of times, but not yet got round
to it.

Knowing which methods should be prioritised for implementation (i.e.
because people actually use them in real-world code) would be very
useful.  And patches even more so!
