/**
 * Helper class used to solve [WSTX-174]: some older AppServers were
 * shipped with incompatible version of QName class, which is missing
 * the 3 argument constructor. To address this, we'll use bit of
 * ClassLoader hacker to gracefully (?) downgrade to using 2 arg
 * alternatives if necessary.
 *<p>
 * Note: choice of java.util.logging logging is only based on the
 * fact that it is guaranteed to be present (we have JDK 1.4 baseline
 * requirement) so that we do not add external dependencies.
 * It is not a recommendation for using JUL per se; most users would
 * do well to just use slf4j or log4j directly instead.
