Mapping maps changes statically declared types during runtime without warning
-----------------------------------------------------------------------------

                 Key: OPENJPA-1199
                 URL: https://issues.apache.org/jira/browse/OPENJPA-1199
             Project: OpenJPA
          Issue Type: Bug
    Affects Versions: 1.2.1
         Environment: Ubuntu 9.04 x86_64 / jdk-7-ea-bin-b62-linux-x64-25_jun_2009.bin
            Reporter: Daniel Kulesz
         Attachments: jpatest.zip

When using map mapping in OpenJPA, statically declared types in Sets are changed to types
of attributes they refer to in other Entities during runtime without warning. This can  lead
to (rather unexpected) Class cast exceptions. 

The attached (commented) example code demonstrates the problem.
