Description ArronM CLA 2010-06-29 12:46:05 EDT 
Build Identifier: SWT3650

We've had several users reporting crashing when the Browser widget is used by our app. One of them sent us his Crash Log.  Hopefully you can make more sense out of it than I can.  I'm not sure when the user is actually getting the crash, other than they are using the Browser widget at the time.  Java 1.5, Carbon, OSX 10.4.11.

Reproducible: Couldn't Reproduce
Comment 1 ArronM CLA 2010-06-29 18:13:21 EDT 
Found a URL that consistently crashes.  Here's a snippet:

Users also reported this only started to happen after they updated Safari.  I can reproduce on Version 4.1 (4533.16)


	public static void main(String[] args) {
		Display display = new Display();
		final Shell shell = new Shell(display, SWT.SHELL_TRIM);
		shell.setLayout(new FillLayout());

		Browser browser = new Browser(shell, SWT.NONE);
		browser.setUrl("http://btjunkie.org/?do=help");

		shell.open();

		while (!shell.isDisposed ()) {
			if (!display.readAndDispatch ())
				display.sleep ();
		}
		display.dispose ();
	}
Comment 2 Scott Kovatch CLA 2010-07-14 13:46:18 EDT 
Browser bugs to Grant, but it is Carbon. I can't reproduce this on 10.6.4 and Safari 5, FWIW.
Comment 3 ArronM CLA 2010-08-19 15:19:22 EDT 
Found a potential fix in Safari.java::handleEvent (Webkit.java in 3.7, I believe).  changing the line

	if (typeString.equals(DOMEVENT_FOCUSIN)) {

to

	if (typeString.equals(DOMEVENT_FOCUSIN) || typeString.equals("focusin")) {

and similarly for DOMEVENT_FOCUSOUT/"focusout"  prevents the crash.  No idea if I'm breaking anything :)
Comment 4 Lakshmi P Shanmugam CLA 2018-12-10 06:48:04 EST 
Closing as Carbon is not a supported platform.
