Hi All, I'm not sure if this is the place to report this, but hopefully so. (I did not see a way to create an account or report issues on JBS.)
I am using JavaFX embedded within a Swing application and had found intermittent deadlocks on macOS that I wasn't sure why it was happening. I was finally able to create a minimal working example and have published it here: https://github.com/kunstmusik/ContextMenuHangingTest The switching applications seems to be a key to getting the deadlock to happen. Testing with debugger in Netbeans, when the app freezes, I paused the app and saw this in the Java FX Application Thread stack: "JavaFX Application Thread" at
