I thought that unit tests were run sequentially and not threaded. However, we have an intermittent issue where our Mocks seem to not be getting reset between tests. This results in out unit test and build failing. Here's an example of the error output:

We're running Jersey 2.22.1 and Mockito 1.10.19.
Just for emphasis; Mockito.reset is being called on all the mock objects in between each test:
@BeforeMethod
public void setupMocks() {
reset(catalogManager, engineManager, transformer, conflict, difference, results);
Locked
