SRU: backport the openjdk-15 security release to groovy

Hello Matthias, or anyone else affected,

Accepted openjdk-15 into groovy-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/openjdk-15/15.0.3+3-1~20.10 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-groovy to verification-done-groovy. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-groovy. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

the binary packages for groovy were built in the openjdk-r/ppa ppa with just the security pocket enabled, to be potentially be copied to the security pocket.

the build looks good, and matches the one in hirsute.

All autopkgtests for the newly accepted openjdk-15 (15.0.3+3-1~20.10) for groovy have finished running.
The following regressions have been reported in tests triggered by the package:

libreoffice/1:7.0.5-0ubuntu0.20.10.1 (armhf)

Please visit the excuses page listed below and investigate the failures, proceeding afterwards as per the StableReleaseUpdates policy regarding autopkgtest regressions [1].
