I'm unfamiliar with these details; I found this link helpful: https://www.baeldung.com/java-serialize-lambda Alternatively: if we put `propListener` in BasicPopupMenuUI: then I think serialization will be less of an issue. `JComponent#ui` is transient, so we don't try to serialize it (and all of its other listeners). This way the JPopupMenu will come out on the other side of deserialization using whatever the L&F is in that setup. This feels good-ish to me. (I'm assuming most L&F's extend BasicPopupMenuUI?) This is all just an idea/suggestion; as long as the deserialized JPopupMenu behaves like the original JPopupMenu I think that should be fine. ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/26407#discussion_r2241571712
