A second report of this bug by Pratista via the mailing list:

-----------------------------------

after testing it further with other browsers & JRE version, here is
the result:

FF11 with JRE 6 or 7 still exhibit the same problem
other browser (ie, chrome) with any JRE version doesn't have any
problem

my application uses cakephp + jquery,
after requesting an ajax process with post method,
the applet closes itself after showing some error log.

the problem step by step:
- user click a button.
- jzebra print barcode.
- the ajax process modify (remove / append) some element on the page.
- the applet closes itself.
- applet gone and can't print another barcode.

This bug seems to be a problem with the way ajax, Firefox and Java behave 
together, forcing an unintended reload of the applet.  I'm not yet sure how to 
fix this.

Proposed fix in 1.4.2 by revisiting how init(), start(), stop(), destroy() are 
called per http://www.cafeaulait.org/course/week5/28.html.

This should provide better browser refresh/ajax support and fix what was 
causing getVersion() errors as well as null object errors on Firefox and 
possibly other browsers.

Needs confirmation before closing.

Morning Tres,

I have tried and tested version 1.4.2 this morning and whilst the problem seems 
less frequent the problem is still there.

I've spent some time researching this, and there may be a bug specific to 
certain jQuery versions (bugs are reported against 1.4.x, but marked as fixed). 
 If you are encountering this issue, please post your jQuery version(s) and 
whatever info you may be able to supply.

Version 1.8.0 Added workaround for possible browser lock-up, documented here:
   https://bugs.launchpad.net/ubuntu/+source/firefox-3.0/+bug/331962

One poster suggests this seems to affect many platforms (i.e. Windows) let me 
know if this addresses any of the sporadic lock-up issues.
