Kathey Marsden commented on DERBY-766:
--------------------------------------
Mamta suggested changing JoinNode.getNumJoinArguments() from 12 to 11, which
seemed to fix up the simple test case. Thanks Mamta! I will run the full set of
tests. What is not clear to me is why this change was not needed in the
original change. Trunk returns 11 too, but that change was due to DERBY-1700
removal of a totally different parameter.
