-------------------------------------

             Summary: Bad practice - Method with Boolean return type returns 
explicit null
                 Key: OPENJPA-2206
                 URL: https://issues.apache.org/jira/browse/OPENJPA-2206
             Project: OpenJPA
          Issue Type: Bug
          Components: Enhance
    Affects Versions: 2.2.0
            Reporter: James Carman


FindBugs is reporting this error on our enhanced classes.  Details about the 
error:

A method that returns either Boolean.TRUE, Boolean.FALSE or null is an accident 
waiting to happen. This method can be invoked as though it returned a value of 
type boolean, and the compiler will insert automatic unboxing of the Boolean 
value. If a null value is returned, this will result in a NullPointerException.
