Stacktrace says something is missing at line CNavBarDocument.java:40 that is causing the N.P.E. The rest of the problem could be due to the Java plugin for 1.7 not being trusted by your browser.

In our HTML contains multiple Applets(6-7) when we are trying to access that html New java Console get open. We are keeping the static data into the global varibale. When we access the html New Java console get open and reference of global variable became null on JRE7U13.
Due to that we are getting nullPointerException.

I am not able to find the reason of opening the New Java Console on JRE7U13.

Please help me.
