    FULL PRODUCT VERSION : java version "1.8.0_102" Java(TM) SE Runtime Environment (build 1.8.0_102-b14) Java HotSpot(TM) 64-Bit Server VM (build 25.102-b14, mixed mode) ADDITIONAL OS VERSION INFORMATION : Microsoft Windows [Version 6.1.7601] A DESCRIPTION OF THE PROBLEM : MenuBar instances added to Tab in a TabPane are still referenced if the parent tab or tabpane is closed. Please note that in the provided test case, the Payload is only present to make it easier to see the memory leak in a profiler. The test case was derived from a real world issue, where the MenuBar referenced further Objects due to listeners (lambdas). STEPS TO FOLLOW TO REPRODUCE THE PROBLEM : 1. Open example application 2. Attach jvisualvm and profile memory 3. Press button in UI multiple times 4. Close all open tabs 4. Trigger GC 5. Memory is not garbage collected, Heap dump shows MenuBar items are still referenced. EXPECTED VERSUS ACTUAL BEHAVIOR : EXPECTED - MenuBar instance should be garbage collected when the parent tab is closed. ACTUAL - MenuBar items are still referenced and cannot be garbage collected. See error message below.
