For those who don't know, Bouncycastle is lightweight cryptography API.

Scenario:
We created applet that uses bouncycastle classes to generate digital certificate. My colleague worked on bouncy castle and it was working fine so far. I created new method in applet and signed it with code signing certificate in my machine. I uploaded applet on test server and it thrown error given below.  

Java Release note: Only digitally signed (Code signing) Applet will work 2014 onward

Solution:
After trying all options from internet at last we were clueless. I told him to sign applet in your system. He did it and worked fine. Reason is as follow...

We both having 64 bit system. In my system I installed 32 bit java and he has 64 bit java in his system. Thats the problem may be bouncy castle created using 64 bit Java. If you are getting same issue. Try to sign your applet using 64 bit java from
C:\Program Files (x86)\Java\jdk1.6.0_25\bin\jarsigner.exe
