-------------------------------
> Sampling of VM stats generates fatal log message and skips remaining stats in
> sample

> Key: GEODE-6253
> URL: https://issues.apache.org/jira/browse/GEODE-6253
> Project: Geode
> Issue Type: Bug
> Components: statistics
> Environment: JDK 11
> Reporter: Kirk Lund
> Assignee: Kirk Lund
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.9.0
>
> Time Spent: 40m
> Remaining Estimate: 0h
>
> I've seen several bugs filed for this and then fixed by using
> addIgnoredException.
> Unfortunately, this means that quite a few stats that are refreshed after
> line 624 of VMStats50 are not refreshed. Also it seems silly to keep adding
> addIgnoredException to lots of tests.
> I think the product code should be changed to catch this and workaround it
> (skip the sample and move on to the next stats). At most, this should be a
> `warning` or `info` level statement:
> {noformat}
