This bug was fixed in the package jsunit - 0.2.2-2ubuntu1
--------------- jsunit (0.2.2-2ubuntu1) focal; urgency=medium
* jsunit is unmaintained and hasn't been ported to thunderdird series 78 (https://<email address hidden>/msg05251.html), so it is being removed from the focal archive to allow thunderbird to be updated (LP: #1895643)
