There was a problem hiding this comment.
another way to write this, without a compound expression, would be:
if (Boolean.FALSE.equals(aliasMetadata.isHidden())) {

There was a mysterious failure in an upgrade test. Examining the logs, I found a NullPointerException that wasn't revealed in the test failure message. Fixing the NPE fixed the test.
Should the
