I've just come across an oddity with JavaFX and Swing. When disposing a JavaFX Panel that had been added to a JFrame or JPanel, re-adding a new JFXPanel will throw an IllegalStateException: "Platform.exit has been called". In my case this has happened after I removed some JPanels with JFXPanels inside and then tried to re-add them. Luckily I found a solution in an Oracle Forum.

This is the trace: java.lang.IllegalArgumentException: The observer is null. at android.database.Observable.unregisterObserver(Observable.java:59) at android.widget.BaseAdapter.unregisterDataSetObserver(BaseAdapter.java:42) at android.widget.AbsListView.onDetachedFromWindow(AbsListView.java:2373) at android.view.View.dispatchDetachedFromWindow(View.java:9756) at android.view.ViewGroup

This has been driving me crazy for a few days now. I have an android application that is pretty complex. It uses multiple threads to pull data from a server and populate the SQLite database. I'm using a singleton to reference my extension of SQLiteOpenHelper. I'm opening and closing the database in each of my activities.
