This is a fairly simple workaround for OpenJDK 6/ ubuntu.
I haven't looked at what it would take to replace the rhino-specific
code with the javax.script API equivalent, but I did look into
upgrading rhino or adding rhino to a jvm version that doesn't ship
with a js implementation (such as openjdk 7 built from source). So
far, this appears to be non-trivial, because rhino doesn't have its
own jsr 223 implementation. The two approaches to address this seem
to be to implement the jsr 223 classes for rhino, or use an existing
rhino 223 impl, as described here:
https://bugzilla.mozilla.org/show_bug.cgi?id=379385
I also haven't looked at what other jvms folks are using these days,
and whether they ship with a js implementation. One option would be
to go the other way, and replace the javax.script code with rhino, and
treat rhino as an explicit dependency. This could be the most
flexible and consistent approach across jvms.
