Peter Martinovic commented on OPENJPA-2183:
-------------------------------------------
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.
