Checkstyle 5 chokes on unknown javadoc tags

Since checkstyle 5, if I use "unknown" javadoc tags it gives an
exception for every file:

Got an exception - java.lang.IllegalArgumentException: the name [adm] is
not a valid Javadoc tag name

In fact that is a tag for a custom doclet. Any chance of telling
checkstyle not to panic?
