Status: RESOLVED DUPLICATE of bug 191035

(Core Graveyard :: Java: OJI, defect)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.3a) Gecko/20021212

When running a page with a Java applet and Javascript that calls it, the first
time you call from Javascript to Java, the browser hangs for several seconds
(cursor stays as a hand, and you can't close the browser, or get any
interactivity).  Perhaps the Java plugin (Sun 1.4.1_01) is doing a security
check?  Browser also jumps to 100%CPU for this duration.  

This works fine for 2nd and later calls from Javascript to Java.

This happens in Netscape 7 as well.  It doesn't happen with the same Sun Java in
IE 6.

Reproducible: Always

Attachment: zip of HTML and java applet

with apologies to Sun... Here is a zip of an HTML page and a java applet (based
on Bubbles) that displays the problem.	The first click on the "reset" link
will hang for about 10 seconds.  The applet simply writes "reset" to the
console when it finally gets called.  2nd and later clicks on reset happen
immediately.

javascript function to demonstrate the bug:
The second alert takes a long time on the first execution of the function.
