chrome plugin crashes when calling javascript function

[Lee Quarella]

Binary package hint: icedtea6-plugin

Working with chrome on ubuntu, have a basic java applet and javascript interaction. The javascript to java goes fine, but when I try having the java fire a javascript method, the chrome java plugin crashes. This all works fine in Fire Fox.

The Error:

    The following plug-in has crashed: icedTea NPR Web Broweser Plugin (using IcedTea6 1.9.7 (6b20-1.9.7-0ubuntu1~10.04.1))

The HTML:

    <object height='300' id='thisappletawesome' name='thisappletawesome'type='application/x-java-applet' width='550'>
        <param name='classid' value='java:JSHelloWorld.class'>
        <param name='codebase' value='/java/'>
    </object>

The Javascript:

    function updateWebPage(){
        alert("java is touching me");
        document.thisappletawesome.setText("hihihi")
    }

The Java:

    import java.applet.*;
    import java.awt.*;
    import netscape.javascript.*;
    import javax.swing.*;

    public class JSHelloWorld extends JApplet {
    JTextArea txt = new JTextArea(100,100);

    public void init(){
     JSObject jso = JSObject.getWindow(this);
     try {
      jso.call("updateWebPage", new String[] {"Hihi"});
        }
        catch (Exception ex) {
           ex.printStackTrace();
        }
    }

    public JSHelloWorld() {
        txt.setText("Hello World");
        getContentPane().add(txt);
    }

    public void setText(String s)
    {
        txt.setText(s);
    }

The problem looks like it was with OpenJDK.
     sudo aptitude remove icedtea6-plugin
     sudo aptitude install sun-java6-plugin
Fixed the problem.

I have the same issue using Ubuntu 12.04 Beta 2, 64 bit running Chrome 18.0.1025.142 beta and with IcedTea-Web Plugin (using IcedTea-Web 1.2 (1.2-1ubuntu1)). Java applets crash and a sad white face appears on a black background.

I had no problems using IcedTea plugin 1.1.3- 1ubuntu1.1 with Chrome Beta in Ubuntu 11.10. I've upgraded four computers to 12.04 Beta 2 within the last week. All are using a newer 1.2 series IcedTea Plugin, which was updated in the updates that came out yesterday/last night. I do my own real estate website and use applets for the main navigation, as well as for marquees. The newer version of Iced Tea works perfectly with Firefox in Ubuntu 12.04. It crashed very frequently in Chrome Beta before yesterday's updates. Since the updates, the crashes are not as frequent, but they still occur. Firefox is still fine. I've replicated this on three of the four machines running Ubuntu 12.04. I don't have access to try it on the fourth. I'm sorry, but I'm not a programmer. If you want me to try to run something to check out, please tell me how to do whatever, and I will do it. The site I'm experiencing the issues with is http://www.cbur-ruralproperty.com . The menu is just under the logo. With the present updates I generally, in Chrome beta, need to refresh the page to get the menu to come up. Then if I click on the various links, by about the third or fourth page the plugin crashes.

It is also reproducable at this URL: view-source:https://www.bankid.no/Hjelp-og-nyttige-verktoy/Nyttige-verktoy/Test-din-BankID/

Just loading the page crashes the Java plugin. I guess it is because of the applet trying to communicate with the web page using Javascript calls (there are a lot of javascript and data on the page).

How can this be debugged, how can a stacktrace be found? Chromium does not give any details in its console output, and I see no option to show java console. This is all I see:

***MEMORY-ERROR***: exe[3953]: GSlice: assertion failed: aligned_memory == (gpointer) addr

Hi Matthias & Don,
I'm unable to reproduce this with either the 1.2 that comes with Fedora, or the most up-to-date release of 1.2

Could you please tell me if you can reproduce the error with the current icedtea-web 1.2 that is provided with Ubuntu, and, if you can, build and try the plugin located at http://icedtea.classpath.org/hg/release/icedtea-web-1.3 ?

[Marius B. Kotsbak (mariusko)]

Are you sure this is not a duplicate of bug #838, which seems to be fixed in Icedtea-web 1.3:

http://icedtea.classpath.org/hg/release/icedtea-web-1.3/rev/41f03d932cdf

[Marius B. Kotsbak (mariusko)]

Could you please prepare a package of Icedtea-web-1.3 for Ubuntu? I tried building one but got some troubles, then built it directly from source, but it just crashed the browser tabs of Chromium.

[Marius B. Kotsbak (mariusko)]

I reproduce with 1.2 Ubuntu package, but browser pages just hangs using a 1.3 manually built plugin.

[Don Myers (donmyers)]

With Chrome 21.0.1180.41 Beta, java is not functional. I receive a message that the IcedTea is out of date. All updates from Ubuntu have been applied. I have openjdk-6-jre version 6b24.1.11.3-1ubuntu0.12.04.1. The plugin is IcedTea-plugin1.2-2ubuntu1. Shouldn't this be updated through Ubuntu?

[Adomurad (adomurad)]

Closing because it works for me.

[Marius B. Kotsbak (mariusko)]

Is this still an issue? According to comment #13, it seems to be fixed now.
