[jdom-interest] Possible BUG in XercesErrHandler class

[Govy Munamala]

But the exceptions are already classified as Fatal, Warning and regular 
errors. The "#ELEMENT# must be declared " exception is being raised as a 
recoverable error within Xerces and thus being handed over to the error 
method in XercesErrHandler. Even the org.xml.sax.helpers.DefaultErrHandler 
class is having no op for the methods warning & error.

Is there any other solution to identify the type of exception within the 
programs, because as it stands we cannot introspect the IOException  for 
these ignorable exceptions.

If the design decision is to notify every exception, then the fine 
granularity of the exceptions should be delegated to the calling programs 
for appropriate action instead of flattening it into a generic IOException.

Thanks
