/**
 * Base class for WebDAV exceptions.
 *
 * These are RuntimeExeptions to work around a limitation of
 * Milton. Many operations don't allow exceptions to be thrown. Hence
 * our only chance to report an error is to throw a
 * RuntimeException. However throwing RuntimeException directly will
 * result in an "Internal Server Error" being reported back to the
 * client. Therefore we catch these exception in DcacheStandardFilter
 * and respond with appropriate error codes.
