Description Heiko Behrens CLA 2009-02-10 10:55:05 EST 
At runtime: When evaluating an expression of an extension file the imports another extension that again imports *and reexports* an extension file that is unknown the Exception message is "(null)" without any further help nor stacktrace. The latter is a result of the translation from java stacktrace to "expression stack" and therefore by design.

Please find attached a patch that produces a more meaningful exception that an NPE.
