This isn't Sun's rt-closed.jar, which is proprietary. This is a faked version which is part of the IcedTea build. However, on both IcedTea6 and IcedTea7 this only includes SNMP and sound stubs (and the latter should probably be removed). On IcedTea6, it also includes JNLP. We should look at enabling IMPORT_BINARY_PLUGS=false on IcedTea so these stubs are not needed. -- Andrew :-) Support Free Java!
