The SharingThreadTest is failing occasionally in overnight runs with this message:

javax/management/eventService/SharingThreadTest.java Failed. Execution failed: `main' threw exception: java.lang.RuntimeException: >>> (37) Expected to receive: 10, but got: 0

This is undoubtedly due to the incorrect logic it shared with AddRemoveListenerTest. The latter has been corrected and this one should be corrected too.
