Mike Matrigali resolved DERBY-2894.
-----------------------------------

       Resolution: Cannot Reproduce
    Fix Version/s: 10.3.1.4

This issue no longer reproduces, it must have been fixed by subsequent Collation work, but not sure what change.

> calling DatabaseMetaData.getColumns(null, "APP", "CUSTOMER", "%") returns no rows for a valid APP.CUSTOMER table 
> in ibm142 and sun142 jvms, for databases created with territory based collation, fails in all 3 cases we test in the 
> CollationTest2.java junit test. 
> Since this is a system catalog query I am surprised the result is affected at all by collation, so there may be a derby bug 
> in the metadata routines, or elsewhere. Mamta, could you comment if you believe this should work already - or if there 
> is more work to do in this area. 
> I will soon checkin a test case into the CollationTest2.java unit test that shows this. For now I will either comment out the 
> entire test, or if I can figure out how to not run it on 142 I will do that.
> This issue was first reported as DERBY-2703 but it was reported as a subtask of DERBY-1478. But since it really is a bug, I am re-reporting it at the top level so it can be tracked as open bug.
