However, I don't understand why the test fails. The test is supposed to be executed in a single thread, so why is the exception thrown?31I have tried to run the test (with the exception) in a debugger and I have found that the exception is thrown because the following code in org.mockito.internal.progress.MockingProgressImpl.getConflictingRunnable(MockingProgressImpl.java:77) returns a non-null value:32if (stubbing.getInvocation().getInvocationCount() == 0) {
