Crash with message: Cannot detach thread when there are non native frames on the call stack

[Tran Quoc Anh]

Hi, today after updated robovm to nightly version, my game crash with message "Crash with message: Cannot detach thread when there are non native frames on the call stack" in console. And this's crash log:

My game use libgdx and robovm.

Hi all,

I was just experimenting with threads and RoboVM, and I reproducibly get the same "Cannot detach thread when there are non native frames on the call stack" crash with the following modification of the first example in the documentation

        final Executor executor = Executors.newSingleThreadExecutor();

        button.addOnTouchUpInsideListener((control, event) -> {

            executor.execute(() -> {

                try {

                    Thread.sleep(1000L);

                    DispatchQueue.getMainQueue().async(() -> {

                        button.setTitle("Click #" + (++clickCount), Normal);                                    

                    });

                } catch (InterruptedException e) {

                    Thread.currentThread().interrupt();

                }

            });

        });

Calling sync() instead of async() on the DispatchQueue works fine.

Thanks

Mirko

See https://github.com/robovm/robovm/issues/687. We should have a fix
for this in the next nightly and in the next release.

Great stuff! The latest nightly seems to also have fixed an IllegalMonitorStateException I was getting when trying to use https with a client generated by Apache Thrift.
