OK.  I looked through the code changes but couldn't spot anything obvious.

While I was reviewing, I did notice one unrelated thing.  In your 
original code, you were using Thread.getId(), and -1 as an invalid 
thread ID.  Then you had to change it to System.identityHashCode(thread) 
for 1.4-compatibility.  However, I don't think there's any guarantee 
that identityHashCode can't return -1 (even though it's unlikely given 
that most JVM's implement it as a pointer address), so is the following 
test in RolapStar.clearCachedAggregations still correct?

     if (aggregationKey.getThreadId() == threadId) {
         it.remove();
     }
