Hello,
Thanks for report.
Can you provide the request content that is failing:
- Full URL
- Post body if any
- Headers
- Cookies

and jmeter.log.

Thank you

Hi Ram Yelisetty,

It looks like your request content string contains escape character like '%' and your request content string might be something like this "abc%  @de".

However, java.net.URLDecoder.decode("String") throws exception for such escape 
characters. So Please make sure your request content string does not contain escape charecter(%).
