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.
