Hi!

We're porting a large Swing app to JavaFX for use on Android, and I'm encountering a Stack Overflow in some situations, due to the very small default Android stack size. I've modified the app in a number of other places to spawn threads with larger stacks (for example when deserializing objects with nested components) but can't figure out how or if it's possible to increase the stack size of the JFX thread. As far as I can tell the JFX thread is not the main app thread that's launched, which it's apparently impossible to increase the stack size on, but instead somehow spawned by the JFXPorts Android Launcher, although I couldn't find where exactly that happens.

We're already looking into reducing the number of nested Regions, but it would be touch to guarantee that in all circumstances and in the future.

Anyone know if it's possible to increase the stack size of the JFX rendering thread, or how I'd go about doing that? Stack trace is below.

Thanks!

Yes, that is the answer, we've already added this question to the FAQ, since it gets asked from time to time:
