Mamta A. Satoor commented on DERBY-3823:
----------------------------------------
I am leaning more towards NOT backporting the changes to 10.8. I realize that
in our regression tests, we have run into this intermittent NPE in stress test
for quite a few releases now but we have not heard of this specific NPE from a
user as of yet.
The Derby code we are planning to change is traversed heavily and since the
suggested code change would not have gone through enough testing, I am hesitant
about having it in 10.8 release. In future, if we do come across users who run
into this problem, it will be easy to track this jira down since the NPE stack
trace is clear about where things are going wrong. At that point, we can
consider backporting these changes as needed. Just my 2cents.
