The following signature is pending, but still approved:

: method java.util.regex.MatchResult group int

The first time, I approved it so that it showed up in the "Signatures already approved" list. The next day, the same signature was pending again. After I approved it a couple of times, I tried to use "Approve assuming permission check" instead. Afterward, the signature was listed in "Signatures already approved" and in "Signatures already approved assuming permission check". But every day, this signature is pending again. Some of my jobs which are using this signature are working correctly. Other jobs using this signature are not working correctly because the permission is denied.
