[jira] Updated: (XERCESJ-1076) thread safety issue with schema
validation
[ http://issues.apache.org/jira/browse/XERCESJ-1076?page=all ]
Michael Glavassevich updated XERCESJ-1076:
------------------------------------------
Fix Version: 2.8.0
Description:
Parsing multiple documents in multiple threads with schema validation enabled sometimes fails. The error reported is: org.xml.sax.SAXParseException: cvc-pattern-valid: Value 'en' is not facet-valid with respect to pattern '([a-zA-Z]{1,8})(-[a-zA-Z0-9]{1,8})*' for type 'language'.
The test program I will provide to recreate the problem usually runs without error. It creates a number of threads, and parses the same document in each thread, concurrently.
However, sometimes it fails with the reported error. I have provided a script (runit.sh) that will repeatedly run the program.
The test program is called parseerror.ParseError. It uses an EntityResolver to locate the schema in the classpath.
Typical program output is as follows:
> runit.sh
java version "1.4.2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2-b28)
Java HotSpot(TM) Client VM (build 1.4.2-b28, mixed mode)
