Matrix Parameters are not passed correctly

We are able to reproduce the issue, using a public github project, shared by customer.

1. Create a Maven project in Jenkins. URL of the project is mentioned in another comment
2. Set Goal to "clean install"
3. The name for published artifact, has the properties appended to file-name (See the URL Encoding for ; & = in request.log)

          In request.log, ; is encoded to %3B and = is encoded to %3D for the custom properties only.

          Build properties like build.name, build.number do not have encoding.
