Exceptions from XMLPlatformUtils::initialize and in general

[Dor-Shifer Amit <Am...@comverse.com>]

Hi,
 
Though in the API I can't seem to see that a/m method throws any
exceptions, I see that a lot of test programs in xerces-c's sourse tree
do wrap the call in try/catch. Why is that?
 
Apart from the exceptions mentioned in the API, should a using program
catch any other exceptions? What about OutOfMemoryException?

If you use the default MemoryManager implementation, you could get an 
OutOfMemoryException.  Also, I suspect there are places in the code 
where initialization could throw exceptions, especially if you specify 
the parameter that initializes all statics.

Note that you can install a PanicHandler if you want control over how 
your application reacts to error conditions during initialization that 
are so fundamental that exceptions can't be thrown.  The default 
PanicHandler behavior is to call exit().
