RFR: 8311514: Incorrect regex in TestMetaSpaceLog.java

Thu Jul 6 09:31:11 UTC 2023

The regex in jtreg test `TestMetaSpaceLog.java` is intended to capture the metaspace size before and after the reclamation. But it captures the wrong value. which might cause this test to always pass. The results of the capture can be displayed using a visualization tool.
