Java, Tomcat: invalid character present in cookie value

I am working on a SPring -MVC project where I am trying to set a cookie. I am using Tomcat7 and I have already set the cookie processor in context.xml on Rfc6265CookieProcessor. I am currently getting the following error.

Error Log:

HTTP Status 500 - Request processing failed; nested exception is java.lang.IllegalArgumentException: An invalid character [44] was present in the Cookie value

type Exception report

message Request processing failed; nested exception is java.lang.IllegalArgumentException: An invalid character [44] was present in the Cookie value

description The server encountered an internal error that prevented it from fulfilling this request.

exception

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.IllegalArgumentException: An invalid character [44] was present in the Cookie value

Cookie values that need to be set: spaces are actually not there, got them, reformatted in IntelliJ to get them in one paragraph:
