Re: xalan-j2 D7: StreamSource cannot be kept?

I am looking but I don't see how to close the StreamSource.  I am setting it
to null but that does not help.  In the examples I always see something
like:

Templates templates = tfactory.newTemplates(new StreamSource(xslID));

I assume that by doing it this way the StreamSource gets closed
automatically?  How would I close the stream if I created the "new
StreamSource(xsl)" somewhere else?

thanks for the help,
-Rob
