It supports bits of it:

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

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!
