You'll find that recent versions of Jess will do the conversion
automatically. Download a newer version.

Use store() and fetch to transfer things between Java and
executeCommand-type things to avoid letting Jess reparse your nicely
tokenized multifields.
I have not done anything to allow the user to replace the tokenizer,
as it's very tricky, and filled with exceptions and special cases to
properly handle CLIPS syntax. The changes you proose might have bad
consequences elsewhere.
