Description

MCHECKSTYLE-250 fix does not check for null values, only for invalid URL. This patch checks for null values and fixes the original problem, and emits a warning if the license file is missing (but does not kill the checkstyle process or site build). Interestingly - this error only occurs on 'mvn site', not on 'mvn checkstyle:checkstyle'.
