Subject [jira] Updated: (MUSE-270) EMPTY_DOC thread stability issues
Date Fri, 11 Apr 2008 10:54:04 GMT

     [ https://issues.apache.org/jira/browse/MUSE-270?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Chris Twiner updated MUSE-270:
------------------------------

    Attachment: 270tsPatch2.txt

This patch is provided by Rich against a clean pull from the 2.2.0 branch and my src changes.
 (I also now know that I must always create a neww fresh pull of the branch before svn diffing
:-) so future patches may also come directly from me).

Note so far I have not even started to cover the following modules src folders for code changes:

  muse-osgi-soa-axis2
  muse-util-logging
  muse-util-qname

and previews:

  muse-platform-jaxws
  muse-wsrt-api
  muse-wsrt-impl

In all cases I'll try and get them done some time in the next weeks.

> This bug is being opened to track the EMPTY_DOC thread stability issue currently being
discussed on the muse-dev mailing list.  XmlUtils provides EMPTY_DOC as a scratchpad instance
of a DOM Document for creation of elements.  This has been shown to cause exceptions in a
multi-threaded environment.  The issue is compounded by the widespread use of EMPTY_DOC in
the code due to its convenience and the reduction in object creation when constructing XML
fragments.
