While working on a memory leak for ChoiceBoxSelection
(https://bugs.openjdk.java.net/browse/JDK-8241455) I wrote a test
covering the same issue in other controls with selection- and
focusModels (the latter if available). Turned out it fails for
- TreeView selection- and focusModel
- TreeTableView focusModel
- TabPane selectionModel
all register listeners (eventHandler in the case of TreeView) to
properties of the control with strong references, the fix is similar:
use weakListeners (if that's the outcome of fixing choiceBoxSelection)
How to procede? Options seem to be
- one issue/pull request per control
- bulk issue/pull request for the all similar (keeping the current for
ChoiceBox as is)
- include all into the current issue/pull request for ChoiceBox
- other?
