back/forwards mouse buttons cause applet to crash

[robert245]

Description I have a Logitech G502 mouse, which has side buttons usually mapped to go back/ go forwards). There have been times I've accidentally clicked these buttons while interacting with a cheerpj applet, and it causes an unchecked exception to kill the current thread.

This can be reproduced in the official cheerpj demos, which I'll describe below

Steps to reproduce (assuming you have a mouse with forwards/back buttons)

1. Go to applet (e.g https://labs.leaningtech.com/cheerpj3/tutorials/applet#the-result) and wait for applet to load
2. Use mouse-back button

Expectation

• Mouse-back action is ignored

Actual:

• Applet stops responding to actions (cannot click most buttons)
• Stack trace emitted to console {code} Exception in thread "Thread-2" java.lang.IllegalArgumentException: button doesn't exist 0 at java.lang.Exception.(Unknown Source) at java.lang.RuntimeException.(Unknown Source) at java.lang.IllegalArgumentException.(Unknown Source) at java.awt.event.InputEvent.getMaskForButton(Unknown Source) at com.leaningtech.cheerpj.MouseState.sendMouseEvent(Unknown Source) at com.leaningtech.cheerpj.CheerpJDisplay.sendMouseEvent(Unknown Source) at com.leaningtech.cheerpj.CheerpJToolkit$1.run(Unknown Source) {code}
