-------------------------------------
Summary: Very high memory usage validating XSD 1.1 (+memory leak)
Key: XERCESJ-1684
URL: https://issues.apache.org/jira/browse/XERCESJ-1684
Project: Xerces2-J
Issue Type: Bug
Components: JAXP (javax.xml.validation)
Environment: windows java 1.8
Reporter: Simon Sprott
Priority: Critical
Attachments: SAFTPT_1_04_01_XSD11_Full.zip, tmp.zip
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 quanity 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).
