GHA failure
One is the well known wget error, unrelated.
The other is a jtreg failure, serviceability/sa/CDSJMapClstats.java fails.
ACtually it throws SIGBUS, and then terminates with 
IOException: LingeredApp terminated with non-zero exit code 137

I would not expect this change to affect CDSJMapClstats, but please have a second look and best restart this test.
