Milosz Tylenda commented on OPENJPA-525:
----------------------------------------
Could you please check the possible impact this change has on the streaming LOB
functionality? Not very sure it is because of this this but that functionality
is now broken. The tests are named ReaderLobTest and InputStreamLobTest.
Although they are not executed by the test suite, the functionality is
described in user manual (I have no idea why someone named the tests that way
causing the test suite to skip them - oversight?). Note that the tests require
a database other than Derby to run on.
One of stack traces I am receiving with MySQL:
