FULL PRODUCT VERSION : JRE version 6 Update 10 (build 1.6.0_10-rc-b28) ADDITIONAL OS VERSION INFORMATION : Windows XP Professional, version 5.1, (2600.xpsp_gfe.070227-2300:Service Pack 2) A DESCRIPTION OF THE PROBLEM : When JApplet uses netscape.javascript.JSObject.call()-function, Internet Explorer 6 stucks. Javascript method eval functions normally. I use Microsoft Visual Web Developer 2008 to launch the aspx-page. The web page-applet system works normally in JRE 1.6.0_05 and also worked normally in JRE 6 update 10 build 14 (beta) before I updated to RC. ACTUAL - IE 6 gets stucked. Only Windows Task Manager can stop html-page. REPRODUCIBILITY : This bug can be reproduced always. ---------- BEGIN SOURCE ---------- import javax.swing.JLabel; import javax.swing.JPanel; import netscape.javascript.JSObject;//...jre/lib/plugin.jar public class TestApplet extends javax.swing.JApplet{ public void init() { try { java.awt.EventQueue.invokeAndWait(new Runnable() { public void run() { System.err.println("Thread = " + Thread.currentThread()); initComponents(); startProgram(); } }); } catch (Exception ex) { ex.printStackTrace(); } } public void startProgram(){ try { JSObject win = JSObject.getWindow(this); if (win != null){ win.eval("alert('Javascript Alert')"); win.call("FunctionX", null);// Call FunctionX() in HTML page } } catch (Exception ex) { System.err.println("This browser may not support Java to Javascript communication"); } } private void initComponents() { JPanel jp = new JPanel(); JLabel jl = new JLabel("This is JLabel"); jp.add(jl); this.getContentPane().add(jp); } public void myFunction(){ try { JSObject win = JSObject.getWindow(this); if (win != null){ win.eval("alert('I got the message')"); } } catch (Exception ex) { System.err.println("This browser may not support Java to Javascript communication"); } } } and html-page <body> <form id="form1"> <div> <H1> Test Applet </H1> <br /> <script> functionX(){ document.TestApplet.myFunction(); } </script> <APPLET MAYSCRIPT CODE=TestApplet.class NAME=TestApplet archive="TestApplet.jar" WIDTH=100% HEIGHT=90% </APPLET> </div> </form> </body> </html> ---------- END SOURCE ---------- Release Regression From : 6u7 The above release value was the last known release where this bug was not reproducible. Since then there has been a regression.
