I think it was a nonstandard extension to Rhino to read compressed
javascript.

Yes. All you need to do is replace the call to Context.compressReader()
with a dynamic lookup. There's an example at
http://fisheye5.cenqua.com/browse/dwr/java/org/directwebremoting/impl/ShrinkSafeCompressor.java?r1=1.1&r2=1.2&u=-1&ignore=&k=o
which shows exactly how to use Context.class.getMethod("compressReader",
and
compressReaderMethod.invoke
