---------------------------------------------------------------

I ran into this bug while trying to fix DERBY-3650 (thus the name of the attached test case).
 The testBlobSelect*Commit() and testClobSelect*Commit() cases where a commit is performed
after finishing with the object show this bug.   If I get time I will narrow down/rename the
test, but
figured it was better to post what I had than wait.  

I am pretty sure that this commit issue is separate from the multiple reference issue, that
is the point of DERBY-3650.
