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.
