Is there any way we could get access to that test application? I kinda
suspect some sort of classloader issue, as I can't see how the
isManagedType() call would otherwise fail.

Also, can you work around it by setting the
openjpa.RuntimeUnenhancedClasses property to 'disabled'?

IIRC, OpenJPA does not currently support multi-column unique
constraints. I think that there is work in progress to resolve this,
though.
