I should note, there is a memory leak still when using `Disposer`. Each time content is switched, but the `SwingNode` is re-used, a `DisposerRecord` is created that only gets cleaned up when `SwingNode` goes out of scope. In other words, a million content changes will leave behind a million `DisposerRecord`s. So, either there needs to be a `removeRecord` added to `Disposer`, or you could switch to the `TreeShowingProperty` solution. ------------- PR Comment: https://git.openjdk.org/jfx/pull/1219#issuecomment-1687998468
