Description
[This CR is being filed under hotspot/runtime per request from [~dcubed]. Please do not move.]

SA has a number of tests that purposely generate core dumps to run SA commands against. Usually these core dumps only take a few seconds, and at most a few minutes. However, on OSX for unknown reasons they occasional take a very long time, even well over one hour. This results in the SA test timing out.
Comments
Looks like I missed that one with the problem list update. I was just focused on the SA tests. I'll file a subtask to remove it from the problem list.

These tests are no longer problem listed (changes made in JDK-8349684) and the problem no longer reproduces. It seems to have been an issue with macOS 11, which we no longer support. Closing as "Cannot Reproduce".
