Simon Sprott updated XERCESJ-1684:
----------------------------------
Description:
using the 1.1 code branch built from
http://svn.apache.org/repos/asf/xerces/java/branches/xml-schema-1.1-dev
Using the built in sample validator
java jaxp.SourceValidator -xsd11 -a "SAFTPT_1_04_01_XSD11_Full.xsd" -i "tmp.xml"
The validation consumes huge amounts of memory (breaks at 10 GB on my system),
on smaller sample files validation does complete, but still consumes a very
large quantity of memory.
Furthermore it seems to retain the memory allocated via a reference in
org.eclipse.wst.xml.xpath2.processor.internal.DefaultRSFactory._factory after
the validator has completed (this is not evident in the cmd line sample as the
process ends, but I have observed in in my own code).
If I was to guess I would say that the results of the XPath queries are being
cached via DefaultRSFactory and never released.
