(The automatic analist thinks this is DERBY-2751, but that doesn't look right).

This is the stack trace:

1) 
testTableFunctionInJar(org.apache.derbyTesting.functionTests.tests.lang.DatabaseClassLoadingTest)java.sql.SQLException:
 The class 'DummyVTI' does not exist or is inaccessible. This can happen if the

I think this is due to the check-in for DERBY-4126. 

Note: I see the same behavior with on the 10.5 branch. I noticed the change was 
backported to 10.4, so I assume it'll show up there. But I did not actually 
test that.
