@Gail Badner You obviosuly have a bug in the key management routines somewhere and this bug seems to occur in different situations. This bug is now more than five years old. If removing my test case from the issue helps you to solve it, please feel free to do so.

Looking back into the history of the bug, I would in that case however assume that the bug will be left dormant for a few more years and then someone will suggest to close it, since you don't know if it still affects Hibernate 6.
