Are you sure that Context.enter gives you an exception as well?

You should not cache the results of Context.Enter() or minimize number 
of its calls, it is cheap even under JDK 1.1 and you should always use
Context cx = Context.enter();
try {
	....
} finally {
	Context.exit();
}
when you need Context objects.

To minimize number of Context.initStandardObjects() see 
http://mozilla.org/rhino/scopes.html and in particular "Shared Scope" 
session there.
