Java SecurityException : signer information does not match

Java SecurityException : signer information does not match

Cause :

It is happening due to loading of same jar  with multiple versions .

Example :

 In one of my case I faced the same issue.  I have "httpclient-4.1.2.jar" and "httpclient-4.0.jar" jars in my lib folder . Due to this , while loading the jar files , http client is verifying the signature signed by apache. It is getting error due to different certificates from two jar files.

Solution:

 Just remove the one of the jar , in my case I removed old version jar.
