[JAVA] Be careful about upgrade if you use | etc. in the URL of Tomcat

From Tomcat 8.0.39, 8.5.7, 7.0.73, it is a specification that throws an error if the URL contains | etc. Be careful if you are involved in maintaining legacy applications.

java.lang.IllegalArgumentException: Invalid character found in the request target. The valid characters are defined in RFC 7230 and RFC 3986
