New:
* Fixed deadlock in HTTP client stack
* Fixed synchronization order to avoid deadlock while locking the parent

Since 2.2.1 release:
* Fixed RelocateFrame to accomodate new ipv6 scan of host in URL 
* Fixed a potential leak (never emptied hashtable) in HttpManager 
* Error reported when an error occur in the file system does not display the
      PATH any longer to avoid disclosing
* Fixed ZipFrame to allow automagic destruction of stale entries in the 
      underlying zip 
* Fixed directory index of ZipDirectoryResource, to delete and get size
      information the right way 
* Memory and performance upgrade of the infamous CommonLogger and 
      ExtendedCommonLogger, who were the primary culprits in the memory usage 
      once the stores are loaded.
* Redid the InetAddress dump in the logger as well as the status code dump 
* Fixed reuse of connection in the HTTP Client stack, by using jdk1.4 method 
      on socket (uses reflection to keep the code backward compatible) 
* ServletWrapper now take the feeding thread from a thread cache 
      (avoid keeping too many open threads)
* Fixed servlet wrapper to close the input stream when needed, also when a
      relocate or an error is triggered from the servlet, an exception is 
      raised if the client already got (part of) the reply.
* Special files "aux", "con", etc. can no longer be created by the indexer 
      on windows platform (still possible on other platforms as those files 
      are not special there). 
* URL in jdk1.4 can have an empty file element, it is now translated to 
      '/' for all methods but OPTIONS, where it is '*' 
* Integrated cookie parsing patch contributed by Julien Mudry <jmu@elca.ch> 
* Various updates in the HTTP stack, to consume less memory and use 
      non-deprecated Date API. 
* Fixed HttpURLConnection getContentType was raising an exception rather than 
      returning null 
* Fixed ContentLengthInputStream, it now send an IOException when the stream
      is cut too early in read()
* Implemented JigsawHttpServletRequest setEncoding and other servlet 2.3 API
      methods 
* Fixed JigsawHttpServletRequest getCharacterEncoding to return null when 
      undefined instead of the iso-8859-1 default
* Fixed Base64Decoder based on Jeffery Collins <jcollins@boulder.net> 
      original patch 
* Fixed JigsawHttpServletResponse, it now checks that the stream has been
      commited before (wrongly) barfing
* Solved the deadlock problem with negotiated frame, directory listing, 
      and everything that needs backward traversal of the resource tree. 
* Fixed the default encoding used in JigsawHttpServletResponse per 
      servlet 2.3 javadoc 
* Ensure that keys in the ResourceStoreManager are not used twice when 
      generated 
* Added a way to optimize by not unloading big stores, depending on a 
      tunable limit. (org.w3c.jigsaw.storesize= property)
* Fixed RedirectedFrame to avoid ipv6-like hosts when it is a ipv4 one. 
* Removed potential conflicting Connection: header values in the HTTP client
      stack during discovery of HTTP capabilities
* Deadlock fixes in the HTTP client stack 
* Added more servlet 2.3 supported methods.
