Indeed, from my understanding, it's necessary because of the way parameters are retrieved: https://github.com/Jasig/java-cas-client/blob/master/cas-client-core/src/main/java/org/jasig/cas/client/util/CommonUtils.java#L334

Thanks for reminding the question I had for @battags: is the test on the query string really necessary in this ```safeGetParameter``` method?
