--- Comment #18 from Mark Thomas <ma...@apache.org> ---
Thanks for the test case.

Your analysis was heading in the right direction but missed the real root
cause. The problem was the incorrect default implementation of
ELResolver.convertToType(). It failed to call
context.setPropertyResolved(false). This meant older ELResolver implementations
that inherited this method would return null and if
ELContext.getPropertyResolved() was true, that null was treated as a valid
conversion triggering the NPE.

This has been fixed in trunk and 8.0.x for 8.0.23 onwards.
