UnresolvedType#getDimensions uses uncompiled regex, resulting in 97% of memory allocated in Pattern.compile

UnresolvedType#getDimensions introduced in 6e79467 uses an uncompiled regex. After upgrading to a version with this change, my test suite allocates 97% of its memory - 98.2GB - in Pattern.compile calls from that method.

Good catch, thank you very much. Without having studied the code in detail, a quick glance at the changeset seems to imply that this might be fixable by compiling the regex. An automated test reproducing and verifying the excessive memory consumption would be nice.

Please note my July 2024 message to the aspectj-users and aspectj-announce mailing lists regarding my situation as an AspectJ maintainer.

I'm afraid I won't have time to provide a test. But here's a screenshot of the profiler:
