If null is a valid and expected return value, why would
XMLReader.setEntityResolver throw a NullPointerException if you tried to
set the ER to null? How would I reset it to the XMLReader's own default
resolution?
A workaround might have been:
EntityResolver defaultResolver = xmlReader.getEntityResolver();
xmlReader.setEntityResolver(specialCaseResolver);
//do stuff
xmlReader.setEntityResolver(defaultResolver);
but the defaultResolver would be null if the internal default is being
used. If the internal default is considered registered, then
getEntityResolver () could never return null. Right?
