[ANNOUNCEMENT]: XML Commons External 1.4.01 now available

[Michael Glavassevich]

Hi everyone,

The XML Commons team is pleased to announce that version 1.4.01 of XML
Commons External is now available. This release updates the XML APIs to
JAXP 1.4 and also introduces the StAX 1.0 and the Element Traversal APIs.
XML Commons External 1.4.01 will be included in the upcoming release of
Xerces-J 2.10.0.

Specifically, the changes introduced in this release are:

* Added classes and method signatures introduced by JAXP 1.4.

* Added the StAX 1.0 API (JSR 173). Sources based off of the distribution
from Apache Geronimo.

* Added the Java Language Binding for the Element Traversal API
(org.w3c.dom.ElementTraversal).

* Added default implementations to SchemaFactory for the XML Schema 1.0 and
1.1 language identifiers.

* Fixed bugs in SchemaFactory and XPathFactory which caused them to always
use the system ClassLoader when searching for META-INF/services files
instead of the ClassLoader that would be used to load the concrete factory
class.

* Updated each of the JAXP factory classes so that they treat an empty
string value for their system property as if it had not been set.
Previously the factories would make a futile attempt to create an instance
of a class named "" and then fail.

* Fixed the FactoryFinders so that they no longer catch and ignore
ThreadDeath and serious VM errors such as an OutOfMemoryError or a
StackOverflowError.

* Fixed the default implementation of DatatypeFactory.createDurationDayTime
(long) so that it behaves according to the JAXP specification. Previously
it was just delegating to DatatypeFactory.newDuration(long) which has
different behaviour than the createDurationDayTime method.

* Corrected the default implementations of
DatatypeFactory.newDurationYearMonth() and
DatatypeFactory.newDurationDayTime() so that they behave according to the
JAXP specification. These methods must reject lexical values which are not
valid instances of xs:yearMonthDuration and xs:dayTimeDuration. They were
not doing so before.

* Fixed bugs which could cause NullPointerExceptions to be thrown from the
default implementations of Duration.getYears(), Duration.getMonths(),
etc...

* Fixed bugs in the DatatypeFactory.newDurationDayTime() and
DatatypeFactory.newDurationYearMonth() methods where BigIntegers were being
created for DatatypeConstants.FIELD_UNDEFINED values instead of assigning
the value to null in the Duration.

* Implemented minor performance improvements in XMLGregorianCalendar.equals
() and Duration.equals(). If the given object is "this" object return true
immediately.

* Eliminated an unnecessary conversion to String in Duration.multiply(int).

* Updated the File to URI conversion code in StreamResult so that it is
consistent with StreamSource.

* Fixed miscellaneous typographical errors in the Javadocs.
