Subject [ANNOUNCEMENT]: Apache Xerces-J 2.10.0 now available
Date Sat, 19 Jun 2010 03:32:03 GMT
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 Bnger]

* 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 
Bnger]

* 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 
Bnger]

* 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 Bnger, Arthur De Magalhaes, Mukul Gandhi, Sandy Gao, 
Michael Glavassevich, Khaled Noaman]
