That is not a correct use of 'affects' in Launchpad.  This bogs down the UI
and makes it difficult to interact with this bug.

The Java package undergoes extensive testing as part of an SRU process, and
this is not the only change pending for openjdk-lts.  The straightforward
workaround in the meantime is to make the same change as described in https://bugs.launchpad.net/ubuntu/+source/openjdk-lts/+bug/1788250/comments/8
locally in your own config file.
