Applets are not loaded with Netscape 6.01 using Java Plug-in Merlin Build 63

Platform : Red Hat 6.2
Browser : Netscape 6.01

Applets using Java Plug-in Merlin build 63 with Netscape 6 on Red Hat 6.2 are not loaded .This behaviour is same with / without MAYSCRIPT=TRUE in the object aand Embed tags and throws the following messages in the Java Console.All our
test cases are using EMBED/OBJECT TAG were working fine with the earlier build ,The same applets are not loaded with Merlin Build 63.

The applet sometimes are loaded with Just Applet Tag but still throws
the same messages in the Java Console.I also noticed that the browser
is hanging with EMBED/OBJECT tags without MAYSCRIPT=TURE

Also see the Bug Id# 4452614

The Following are the messages in the Java Console :
