Henri Biestro commented on JEXL-67:
-----------------------------------
Any comments on the patch ? it cleans up the visibility of some methods and
masks using the Void.class as a signature for 'null' arguments (parameters ie
formal can not be null).
> 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
>
> Attachments: JEXL-67.patch
>
>
> 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.
