Currently working on two related issues:https://bugs.openjdk.java.net/browse/JDK-8187309: TreeCell must not change data of treeView https://bugs.openjdk.java.net/browse/JDK-8187473: TreeView must have default commit handler
which are so intertwined that there's no way to fix one without the other (we must have a default commit mechanism in place at any time). I could merge them in the PR (also-fixes), but would feel cleaner to merge in JBS, if possible.
