Description

Since a few days the test 'TestMemoryUsage.test002' fails randomly.

The process tested by this junit test look to use more memory than expected:

Abnormal memory use for Java Composition Discoverer 175 > 100\ Abnormal memory use for Java Composition Discoverer 106 > 100\ Abnormal memory use for Java Composition Discoverer 107 > 100\ Abnormal memory use for Java Composition Discoverer 154 > 100\ Abnormal memory use for Java Composition Discoverer 116 > 100\ Abnormal memory use for Java Composition Discoverer 101 > 100

No code have been modified. It may be caused by the recent use of Java 1.8 or by an update of release train component.

Further more this test cannot be really accurate. (Memory tracking is populated by other threads and by the garbage collector random behavior.)

The less worth solution is to increase the threshold to 180Mo.
