Re: Is saxbuilder safe for multi-threaded (concurrent) use?

SAXBuilder is *not* thread-safe, but it is reusable....

i.e. you need one SAXBuilder per thread, but after parsing something, you
can reuse the builder for the next parse.

You can run many different SAXBuilders 'in parallel', just so long as no
specific SAXBuilder instance is referenced from different threads.

For improved performance set the fast reconfigure and reuseParser flags on
the builder:

builder.setReuseParser(true);
builder.setFastReconfigure(true);
