FULL PRODUCT VERSION :
java version "1.5.0_12"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_12-b04)
Java HotSpot(TM) Client VM (build 1.5.0_12-b04, mixed mode, sharing)
1.6.0
ADDITIONAL OS VERSION INFORMATION :
Linux 2.6.18-8.1.6.el5 #1 SMP Thu Jun 14 17:46:09 EDT 2007 i686 athlon i386 GNU/Linux
EXTRA RELEVANT SYSTEM CONFIGURATION :
Mozilla Firefox 1.5.0.12, Java(TM) Plug-in 1.5.0_12-b04
Seamonkey 1.1.1, Java(TM) Plug-in 1.5.0_12-b04
A DESCRIPTION OF THE PROBLEM :
Can't input any to JEditorPane added by LiveConnect call.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Open test.xhtml. Wait till applet started.
In first JEditorPane you can easily input any text.
Try to add new JEditor pane by clicking 'test' button and go to this pane. You see 2 cursors simultaneously and you can't input any into this new JEditorPane except of nationals characters. JEditorPanes added by clicking 'add' button works good.
The problem is still here in Java SE 6.0. I think the origin of
this issue is that Toolkit.getSystemEventQueue() returns different
objects when called through LiveConnect and from applet main thread.
import javax.swing.JApplet;
import java.awt.Toolkit;
import java.awt.EventQueue;
public class TestApplet
extends JApplet
{
private EventQueue queue;
public void init()
{
queue = Toolkit.getDefaultToolkit().getSystemEventQueue();
}
public void test()
{
EventQueue queue2 =
Toolkit.getDefaultToolkit().getSystemEventQueue();
System.out.println(queue == queue2);
}
}
It prints 'false'.
REPRODUCIBILITY :
This bug can be reproduced always.
