Java crash; nom-ing for blocking fennec
Comment 2 Kevin Brosnan [:kbrosnan] 2012-03-04 13:51:42 PST
Not a top crash, not blocking. Still good to fix though.
Comment 3 Geoff Brown [:gbrown] 2012-03-09 16:30:15 PST
It looks to me like the offending code is:

        if (mIMEState == IME_STATE_DISABLED ||
                keyCode == KeyEvent.KEYCODE_ENTER ||
                keyCode == KeyEvent.KEYCODE_DEL ||
                keyCode == KeyEvent.KEYCODE_TAB ||
                (event.getFlags() & KeyEvent.FLAG_SOFT_KEYBOARD) != 0 ||
                !mKeyListener.onKeyDown(v, mEditable, keyCode, event)) {

suggesting that either event == null or mKeyListener == null.

If event == null, there should have been a NullPointerException at:

    public boolean onKeyPreIme(int keyCode, KeyEvent event) {
        switch (event.getAction()) {
Since that didn't happen, I would conclude that mKeyListener == null. 

Normally mKeyListener would be set in onCreateInputConnection. Maybe it is possible for onKeyPreIme to be called before onCreateInputConnection?

Fetch Android's cached TextKeyListener on key down/up events to avoid nulls.

I'm setting this as verified/fixed since it wasn't reported for the last 4 weeks.
