In our application we load applet to read data from serial ports and USB ports of the machine. The applet code is working fine from past so many years but when we migrated to IE 11.0.44 version, the browser is hanging for 2 to 3 minutes while loading the applet. This is causing issues.
Below is the log file of the Java console. Could you please help us in resolving this issue. Java Plug-in 10.80.2.15 Using JRE version 1.7.0_80-b15 Java HotSpot(TM) Client VM

We are getting the classnotfound exception error when the applet is not loaded properly or it has some communication problem.
