User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.9) Gecko/20020311
BuildID: 2002031115
The following html can cause mozilla to crash:
<html>
<script>
var url = 'http://www.google.com/';
var dest = new java.net.URL(url);
var dis = new java.io.DataInputStream(dest.openStream());
alert('got a socket!');
killme();
</script>
</html>
This does not occur every single time; you have to reload the page a few times
to get it to crash.
Reproducible: Sometimes
Steps to Reproduce:
1. Create a page with the above html
2. View the page
3. If you don't yet see a crash, goto step 2
Actual Results: The web browser will crash.
Expected Results: I'm not sure.

Using debug trunk build 2002-03-14 WinNT. Reassigning to LiveConnect.
When I load the testcase, I see this error in the JavaScript Console:
Error: uncaught exception: java.security.PrivilegedActionException
<<java.lang.reflect.InvocationTargetException>>
and this error in the Java Console:
java.security.PrivilegedActionException:
java.lang.reflect.InvocationTargetException:
java.security.AccessControlException: access denied (java.net.SocketPermission
www.google.com resolve)

Using Mozilla trunk binaries 20020314xx on WinNT, Linux, and Mac9.1
Mac9.1
The test runs fine. No errors in the Java Console, and the test completes
successfully: I get an alert saying, "got a socket!"
WinNT (using Java Plug-in 1.3.0_01)
Same result as with the debug WinNT build: I get errors in the
JS and Java Consoles, and the test does not complete (no alertbox).
However, I am not able to crash...
Linux (using Java Plug-in 1.3.0_01)
The test crashes! Confirming bug.
Unfortunately, I haven't been able to build on Linux in recent days.
Will have to try for a stack trace on someone else's machine.

Sending to OJI. Compare these bugs, where similar Java exceptions
are raised:
bug 113122 "applet error" (this has links to other similar bugs)
bug 121370 "Java exception" (crashes on Linux, only an error on Windows)

The Mac OS X plugin throws similar exceptions, but doesn't crash. It would be
helpful to see a stack crawl of the actual machine crash if possible.

With default security permissions I see 'access denied sun.net.SocketPermission
"www.google.com" resolve' (or smth like this. This is normal.
But when I add
grant {
permission java.net.SocketPermission "*", "resolve, connect";
};
to $HOME/.java.policy, mozilla crashes (Solaris and Linux, java 1.3.1)

Worksforme on Build ID: 2002042510 (0.9.9+) trunk Windows 98. Tried to reload 5
times, no crash.
Reporter, could you install 0.9.9 and Sun Java JRE 1.4, and see if it still
crashes?

I changed var url = 'http://www.google.com/'; to be our internal website and
open All Permission, the script runs well.
The exception happened because that script has not set proxy, dest.openStream()
without proxy will fail.
I think this is not bug, or JPI should use default proxy?

Can't reproduce this bug by using the JRE 1.4.2 beta-b16 and the latest mozilla.

Investigated:
reason is: a exception happened on JPI 's JVM server side, so JPI return a
invaild random value to js/liveconnect as jobject and liveconnect use this value
to get jclass. so this lead to crash.
Mozilla can't check this exception, so this have to be fixed on JPI side.
random value: depend on OS and runtime memory, so it can't reproduce everytime.

works for me, mozilla1.4(debug build) + jre1.5(beta) on both Linux (SuSE) &
Windows 2000.
I got the following message in console:
JavaScript error:
line 0: uncaught exception: java.security.PrivilegedActionException:
java.security.PrivilegedActionException: java.lang.reflect.InvocationTargetException
no crash, no hang.
