Subject [jira] Created: (JEXL-67) Potential NPE in util.introspection.MethodKey
Date Sun, 02 Aug 2009 13:35:14 GMT
Potential NPE in util.introspection.MethodKey
---------------------------------------------

                 Key: JEXL-67
                 URL: https://issues.apache.org/jira/browse/JEXL-67
             Project: Commons JEXL
          Issue Type: Bug
            Reporter: Sebb
            Priority: Minor
             Fix For: 2.0


There are two potential NPEs in util.introspection.MethodKey (discovered by Eclipse)

isInvocationConvertible
isStrictInvocationConvertible

Both methods check for actual == null, but the check is part of a compound and condition so
actual may still be null.

The comments suggest that actual should not be null, so the code should either drop the null
check entirely or check it properly.
