GEODE-6143: remove PowerMock from VMStatsMonitorTest (#2984)
> PowerMock should not be used in Geode tests
> -------------------------------------------
>
> Key: GEODE-6143
> URL: https://issues.apache.org/jira/browse/GEODE-6143
> Project: Geode
> Issue Type: Bug
> Components: build, tests
> Reporter: Kirk Lund
> Assignee: Ryan McMahon
> Priority: Major
> Labels: pull-request-available
> Time Spent: 7h 40m
> Remaining Estimate: 0h
>
> At least one usage of PowerMock in our unit tests is leaking and causing
> other tests to fail with the following stack.
> No further tests should be written using PowerMock and all tests that
> currently use it need to be identified and changed (along with product code
> refactoring) to not use PowerMock.
> We will then remove PowerMock as a dependency from Geode.
