Steps to reproduce:
 1)Install test bundle JDK7u76b03 (download from http://jre.us.oracle.com/java/re/jdk/7u76/promoted/ea/b03/bundles/linux-i586/jdk-7u76-ea-linux-i586.tar.gz) to /demo

 2)Uncompress the jdk demo (download from http://jre.us.oracle.com/java/re/jdk/7u76/promoted/ea/b03/bundles/linux-i586/jdk-7u76-ea-bin-b03-linux-i586-demos-06_oct_2014.tar.gz) to /demo/jdk1.7.0_76

 3)Do plugin soft link from jre to the FF32.0.3: ln -sf /demo/jdk1.7.0_76/jre/lib/i386/libnpjp2.so ~/.mozilla/plugins

 4)We located the applets cases on our server with apache-tomcat-7.0.42 (http://localhost:8080/demo/applets)

 5)Change the security level to medium from the java control panel.

 6)To run the demo please go to http://localhsot:8080/demo/applets/Animator and open each example<N>.html file in browser.
 
Expected result:
the demos should work as expected, there must be no exceptions in the Java Console log.

Actual result:
