Subject [jira] Created: (OPENJPA-137) Perform parameter validation for annotated callback methods
Date Thu, 08 Feb 2007 14:06:05 GMT
Perform parameter validation for annotated callback methods
-----------------------------------------------------------

                 Key: OPENJPA-137
                 URL: https://issues.apache.org/jira/browse/OPENJPA-137
             Project: OpenJPA
          Issue Type: Sub-task
          Components: jpa
            Reporter: Kevin Sutter
            Priority: Minor


This is a follow-on Issue to OPENJPA-133.  Issue 133 was concerned with properly processing
the xml configuration of callback methods.  As I was experimenting with that scenario, I discovered
that our processing for annotated callback methods and xml callback methods is not consistent.
 While we do parameter validation for the xml-configured callbacks, we do not do any validation
of the annotated callback methods.  We just assume that the signature is valid.  An incorrectly
configured annotated callback method is not detected until runtime and then the user will
get an IllegalArgumentException.  It's good that we eventually catch and log this condition,
but if we could do the validation earlier like we do for xml-configured callbacks, the user
will know about the problem much earlier in the process.
