Why is "[Checkboxes] is EMPTY" from one day to the next not working anymore?

Question

Hi, I used in a JQL following syntax:

""Regression test done[Checkboxes]" is EMPTY", default value of this checkbox is empty.

For several weeks this jql showed me the expected result(a list with all tickets where the checkbox is empty).

But from yesterday on it shows me now 1000+ more tickets, which have this checkbox not empty.

Do you have any idea to solve this?

Thanks ;)

seems to me as if JIRA makes changes to their JQL without backward compatibility. Haven't seen anything in release notes.

Seems that I've ran into a similar issue:

How to inform Atlassian directly, so that they know that there is a bug?

Adding that I just noticed a 400 "jqlTooComplex" error from secure/QueryComponent!Jql.jspa
