Description

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.
