Description

QueueMetrics holds its data in a static variable causing metrics to bleed over from test to test. clearQueueMetrics is to be called for tests that need to measure metrics correctly for a single test. jdk7 comes into play since tests are run out of order, and in the case make the metrics unreliable.
