Description

According to the documentation (SAX2 Programming Guide and Xerces-C++ Documentation), the setFeature() method of SAX2XMLReader is supposed to handle changes of the feature "http://apache.org/xml/features/validation/use-cachedGrammarInParse" as a no-op. Instead of doing so, it throws an exception, even if the feature is set to its current (valid) value.

In my eyes, setFeature() should throw a SAXNotSupportedException only if the user tries to set the feature to a value different from its current value, and do nothing otherwise.

If the implemented behavior is intended, the documentation should be updated accordingly.
