Which JRE classes are implemented? about j2cl

[tbroyer]

The emulation library actually comes from GWT: https://github.com/gwtproject/gwt/tree/master/user/super/com/google/gwt/emul
When we don't forget about it, we generate a list of the emulated classes and methods at release time and publish it at http://www.gwtproject.org/doc/latest/RefJreEmulation.html

java.nio.ByteBuffer is supported by PlayN, but PlayN hasnt done any updates to move from JSNI to JsInterop, so J2CL can't use it yet. I started the work in a branch some time ago (https://github.com/niloc132/playn/tree/jsinterop), but haven't completed it. Have been meaning to talk to them to see what approach they want to take with J2CL, and see if it might not make more sense to move java.nio.ByteBuffer and related classes to their own artifact (or into GWT's own JRE support).

I'm tracking this for some other work I'm doing at Vertispan/gwt-rpc#1.
