The Jython interpreter is not thread safe, at least not when run using the Bean Scripting Framework from within an application server.  All of the interpreters seem to share the same PySystemState object. When multiple pages are requested at the same time the interpreters start stepping on one another, creating spurious errors.

We probably need to create our own BSF engine and embed it, similar to
what we did for JSR 223 support. The existing engine
org.apache.bsf.engines.jython.JythonEngine is about 275 LOC, so it
should be a trivial effort.

BSF 3 now uses JSR 223 (, so this looks like a non issue. We have good experience with JSR 223 against Jython, so I think it's safe to close this out now.
