Subject [jira] [Updated] (OPENJPA-2183) Query hint "openjpa.hint.RelaxParameterTypeChecking" is reported to be unsupported and is ignored
Date Tue, 29 May 2012 09:46:24 GMT


Peter Martinovic updated OPENJPA-2183:

(was: Hello Albert. Your patch works, the hint is correctly set on the query. Thank you.

Now there is "java.lang.ClassCastException: java.lang.String incompatible with java.lang.Enum".
It is because QueryImpl at line 826 uses Class.isAssignableFrom for parameter type checking,
I guess it should use its own method QueryImpl.assertValueAssignable, or similar, that respects
the RelaxParameterTypeChecking hint. 

I would consider this task as resolved and suggest to reopen OPENJPA-1889.)
