[ANNOUNCEMENT]: Apache Xerces-J 2.10.0 now available

[Michael Glavassevich]

Hi all,

The Apache Xerces project team is pleased to announce that version 2.10.0
of Apache Xerces-J is now available.

Xerces-J 2.10.0 can be downloaded at: http://xerces.apache.org/mirrors.cgi:

This release introduces experimental support for the XML Schema 1.1
Structures and Datatypes (December 2009) Working Drafts (see
Xerces-J-bin.2.10.0-xml-schema-1.1-beta.zip). It also contains an
implementation of the parser related portions of JAXP 1.4, including
partial support for StAX 1.0 (javax.xml.stream.events only) and a complete
implementation of the DOM Element Traversal API. It contains fixes for
several bugs which were present in Xerces-J 2.9.1, as well as a few other
enhancements and performance improvements.

Specifically, the changes introduced in this release are:

* Added experimental support for XML Schema 1.1 (refer to the documentation
for a list of features supported). [Ken Cai, John Chan, Mukul Gandhi,
Hiranya Jayathilaka, Khaled Noaman, Kun Xu]

* Implemented enhancements to javax.xml.validation that were introduced by
JAXP 1.4, including support for StAXSource/StAXResult as an input/output to
the JAXP Validator, StreamResult as an output to the JAXP Validator and
StAXSource as an input to the SchemaFactory. [Michael Glavassevich]

* Added support for the StAX 1.0 event API (javax.xml.stream.events).
[Michael Glavassevich, Lucian Holland]

* Added support for the Element Traversal API
(org.w3c.dom.ElementTraversal). [Michael Glavassevich]

* Implemented a property for starting schema assessment from a specific
element declaration and enhanced the existing property for starting schema
assessment from a type definition to accept a javax.xml.namespace.QName as
a value. [Michael Glavassevich]

* Added a property for specifying the locale to use when reporting error
and warning messages. [Michael Glavassevich]

* Added support for matching multi-digit back references in regular
expressions. [Khaled Noaman]

* Added a method to the ItemPSVI interface in the XML Schema API to expose
error messages corresponding to the error codes that were already available
in the PSVI. [Michael Glavassevich]

* Implemented native support for UTF-16. [Michael Glavassevich]

* Improved usability of the XML Schema API by updating XSNamedMap and all
of the list type interfaces to extend java.util.Map and java.util.List
respectively. [Michael Glavassevich]

* Improved performance by eliminating excessive calls to
XMLSchemaValidator.findSchemaGrammar() when processing local elements with
no namespace. [Michael Glavassevich]

* Improved recovery from schema loading errors. [Sandy Gao]

* Improved performance of Element.getBaseURI() when the depth of the node
to the document root is longer. [Ludger Bünger]

* Implemented several improvements in the DOM implementation to help the
garbage collector reclaim objects which are no longer reachable by the
application but were held on to strongly by the Document node. [Ludger
Bünger]

* Improved the messages reported for minOccurs/maxOccurs related schema
validation errors. [Michael Glavassevich]

* Fixed problems with regular expression matching where the parser would
hang or cause a stack overflow exception. [Khaled Noaman]

* Fixed a problem where the LSParser repeatedly overwrote a text node child
of an element (rather than appending) when there are multiple text nodes in
the input. [Michael Glavassevich]

* Fixed an infinite loop in XMLScanner which could allow remote attackers
to launch a denial of service attack (CVE-2009-2625). [Michael
Glavassevich]

* Fixed a bug in XSDateTime where getXMLGregorianCalendar() would lose
precision for fractional digits and insert time-zones where there are none.
[Michael Glavassevich]

* Fixed a bug in the DOM implementation where a static text Node field in
AttrImpl broke thread-safety of mutations in independent documents from
within an event listener. This was also a potential memory leak. [Ludger
Bünger]

* Fixed a bug in the SoftReferenceSymbolTable which could cause it to get
stuck in an infinite loop. [Anli Shundi]

* Fixed a bug which could cause an ArrayIndexOutOfBoundsException to be
thrown when adopting a node from a deferred DOM. [Michael Glavassevich]

* Fixed various bugs and made various improvements. [Nathan Beyer, Dave
Brosius, Ludger Bünger, Arthur De Magalhaes, Mukul Gandhi, Sandy Gao,
Michael Glavassevich, Khaled Noaman]
