Gail Badner updated HHH-2572:
-----------------------------
Attachment: HHH-2572.patch
I believe this is the same issue as HHH-2542.
I am attaching a patch for a new test to be added to
org.hibernate.test.component/basic/ComponentTest.testMergeComponent(), based on the test
case provided by Nguyen Hau Giang.
I added the following to Employee:
- an optional component, optionalComponent;
- a Set of Employee objects, directReports.
NullPointerException is thrown when a detached Employee is merged with new element added
to directReports that has a null OptionalComponent. Note that this exception is thrown
when the child element has a null component, as opposed to the grandchild element as
reported earlier.
The stack trace is as follows:

-----------------------------
Attachment: HHH-2572-testcase-corrected.patch
I forgot to add a test file to HHH-2572.patch, so I'm attaching a corrected file,
HHH-2572-testcase-corrected.patch . HHH-2572.patch can be disregarded.
The fix suggested in HHH-2542 (with a correction) fixed this issue and I verified that it
did not break any unit tests. I will attach a patch for the fix to that issue.

---------------------------------------
Thanks a lot,
The patch passed my test case, too.
why this issue is not fixed in version 3.2.4 ?

------------------------------------
Not fixed in 3.2.5, either. We're currently stuck on 3.2.2 until this is fixed.
