Are you running the lastest Jscheme built from CVS. It sounds like
this might be a problem with the class loader extensions that we've
built into Jscheme in the past few months, but I think they were
resolved recently.....

I think the two calls to setContextClassLoader in the file 
jsint/Import.java
should be enclosed in a tryCatch.....
