Greetings, I realise this is now legacy for most people but we still widely use JavaFX 8.
I appear to have discovered a memory leak when skin is changed The constructor com.sun.javafx.scene.control.skin.BehaviorSkinBase.BehaviorSkinBase adds an event listener control.addEventHandler(ContextMenuEvent.CONTEXT_MENU_REQUESTED, contextMenuHandler); However this is never removed in the dispose() which prevents garbage collection of the previous skin. This problem is amplified by fact JavaFX appears to reload skins unnecessarily in a complex use case involving JFXPanel - I've as-yet been unable to produce a SSCCE for this What I've discovered so far - CSS is reprocessed - javafx.scene.CssStyleHelper.canReuseStyleHelper(Node, StyleMap) returns false - node.styleHelper.resetToInitialValues(node); is called which then causes the "stock" skin load - custom skin (-fx-skin in our application CSS) is then loaded - stock skin cannot be GC'd and neither can our custom skin - appears to affect any subclass of BehaviorSkinBase Please could you confirm my analysis of this problem and suggest any workarounds? Regards, Adam
