request to integrate jaxp 1.4.4

[Joe Wang]

Hi,

We're working on jaxp 1.4.4 release and would like to know if you would 
approve integrating it into OpenJDK6. Here are links to jaxp 1.4.4 
source bundle for JDK6 and 7:
Source bundle:

Java API for XML Processing Release Notes*
Specification Version: 1.4
Reference Implementation (RI) Version: 1.4.4
Aug. 24, 2010

The drivers of this release are several regressions from JDK 6 Update 
Release 18 and customer escalations. This release will be integrated 
into JDK6 Update release 23 as well as the current JDK7 development 
branch. Please read below for details on the change log.

Changes and bug fixes in the release:

1.Regressions
Before JDK6 Update 18, bug fixes and improvements in JAXP were 
selectively integrated into JDK6 update releases. During update 18, 
there was a complete synchronization between the JDK and JAXP. Due to 
the number of changes made and the age of these changes, there were 
several regressions found in the release. All of the 
currently-identified regressions have been fixed in this release.


2.Customer escalations
Customer escaltions are generally provided through revision releases 
immediately after they are fixed. The inclusion here is a recount and 
serves as a record for JDK7 integration.

3.Performance improvements
There have been continued effort in performance improvements as a result 
of SPECjvm2008 benchmark tests and analysis.

4.Apache Update
JAXP 1.4 is based on Xerces 2.7.1 and Xalan 2.7. Starting from this 
release, JAXP 1.4.4, we will sync up to Xerces 2.10.0 and Xalan 2.7.1 
over a period of releases in phases. In the first phase of this sync-up, 
all blockers and critical fixes from Xerces and Xalan are integrated.
