This simple code reproduces the problem. Just go back and forth and,
eventually the app crash with OOM error. It took me 34 times with this code
to crash.
public void start() {
if(current != null){
current.show();
return;
}
Form hi = new Form("Map Test", new
BorderLayout(BorderLayout.CENTER_BEHAVIOR_CENTER_ABSOLUTE));
Button btn = new Button("Show Map");
hi.add(BorderLayout.CENTER, btn);
hi.show();
Command back = new Command("Back") {
@Override
public void actionPerformed(ActionEvent evt) {
hi.showBack();
}
};
btn.addActionListener((evt) -> {
Form hi2 = new Form("Map show", new BorderLayout());
hi2.getToolbar().addCommandToLeftBar(back);
hi2.setBackCommand(back);
MapContainer map = new MapContainer(MAP_KEY);
hi2.add(BorderLayout.CENTER, map);
hi2.show();
});
}
I was lucky to get a stack trace only once, not from this code but from
the actual program:
