Thanks for the response. I tried the patch with batik-src-05-03-06
(RhinoInterpreter.java sum = "06257 22" on Linux).
I got the following errors (with "optimizer" directory):

The second exception repeated several times.

Thanks! This patch worked with both Rhino 1.5R4.1 and 1.6R1.
This also fixed "setURI hangs on Linux console [was Re:
org/mozilla/javascript/optimizer Batik hangs?]" in batik-users.
