366778 - no/bad error/exception propagation from java to javascript/liveconnect: raises PrivilegedActionException and InvocationTargetException

Status: RESOLVED INCOMPLETE

(Firefox :: General, defect)

Description

[Karl Ostmo]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.1) Gecko/20060601 Firefox/2.0.0.1 (Ubuntu-edgy)
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.1) Gecko/20060601 Firefox/2.0.0.1 (Ubuntu-edgy)

Exception handling from JAVA to JavaScript (LiveConnect) does not work.  The examples on MDC about "Handling Java Exceptions in JavaScript" fail.

http://developer.mozilla.org/en/docs/Core_JavaScript_1.5_Guide:LiveConnect_Overview:JavaScript_to_Java_Communication#Handling_Java_Exceptions_in_JavaScript

Behavior is the same in Firefox 2.0.0.1 in Linux and Firefox 1.5.0.9 in Windows XP.



Reproducible: Always

Steps to Reproduce:
<script>
try {
	var theClass = java.lang.Class.forName("blah");
} catch (e) {
	alert("The Java exception is:\n" + e);
}
</script>
Actual Results:  
(In an alert box):
The Java exception is:
java.security.PrivilegedActionException: java.security.PrivilegedActionException: java.lang.reflect.InvocationTargetException

This also happens whenever a compiled (.class) Java applet throws an exception.

Expected Results:  
(In an alert box):
The Java exception is:
java.lang.ClassNotFoundException: blah

The error message from the Java console should be propagated to JavaScript in Firefox.  However, there seems to be some kind of communication barrier between the Java plugin and JavaScript.

This bug was reported on Firefox 2.x or older, which is no longer supported and will not be receiving any more updates. I strongly suggest that you update to Firefox 3.6.3 or later, update your plugins (flash, adobe, etc.), and retest in a new profile. If you still see the issue with the updated Firefox, please post here. Otherwise, please close as RESOLVED > WORKSFORME
