If I remember correctly JSBML binds to the binary library
sbml.so/dylib/DLL-- if this is the case you *must* use system
classloader, otherwise the
second run would not be able to relink to the JNI library.
As to the ? - it is not possible to have "local" system properties in Java,
so unless the JSBML allows you to control the xml factory in any way through
it's API you will have to stay with your workaround.
It might be possible to synchronize on the xmloutputfactory instance if it
itself has synchronized methods, but.. if it works now I would just leave it
as it is. ;)
