Jean-Sebastien Delfino commented on TUSCANY-2200:
-------------------------------------------------
The problem is that line in CompositeProcessor (line 82):
// FIXME: to be refactored
private XPathFactory xPathFactory = XPathFactory.newInstance();
Well the FIXME comment is right to the point :)
We shouldn't initialize an xPathFactory statically here as it'll require an
XPath implementation on the classpath (from Xalan for example) to work. It's
really not good to have that static dependency on a 2Mb JAR just for handling
xpath expressions in SCDL property source expressions (see CompositeProcessor
line 262 for some code that uses that xPathFactory).
We should only require an XPath factory when we really need to process XPath
expressions. So - yeah - the FIXME comment at the top is right, this should be
refactored.... cleaned up would be a better way to characterize it.
