build failure related to Unique Constraints

[Rick Hillegas]

I am seeing the following build failure after syncing with the trunk. It 
looks like a test class was not checked in:

   [javac] 
/Users/rh161140/derby/mainline/trunk/java/testing/org/apache/derbyTesting/functionTests/tests/lang/_Suite.java:129: 
cannot find symbol
   [javac] symbol  : variable UniqueConstraintSetNullTest
   [javac] location: class 
org.apache.derbyTesting.functionTests.tests.lang._Suite
   [javac]         suite.addTest(UniqueConstraintSetNullTest.suite());
Regards,
