Since I moved to OpenOffice 4 the extension manager and update icon always creates a dialog with this message "The host name localhost could not be resolved."

I searched the forums and the web in general and did not find this issue.
There is a section below called "Twist" that might be enlightening.

I do not have many extensions and this never happened with OpenOffice.org 3 releases.

Clarification:
OpenOffice.org and the extensions I have work fine!
I just cannot update the extensions!

Extension Status and Info:
I have not been able to update any of my extensions.
The installed extensions are:
American English Spelling Check 1.0
Canadian English Spelling, Hyphenation, and Thesaurus 2.0.0
English spelling and hyphenation dictionaries and thesaurus 
OpenCards 1.5.1
Professional Template Pack II - English 1.0

PDF importer 1.0.4 (Oracle, has message "Error: The status of this extension is unknown", click on it offers "Enable" but given the error who knows if it is disabled or not)

Useful details:
Windows 7 latest updates as of 21 November 2013
Java 7 latest update and JavaFX also
OpenOffice.org
  AOO401m5(Build:9714)  -  Rev. 1524958

Twist:
I use Windows junctions to point to the newest releases of all software so that I do not have to change anything other than the junction when there is a new release the software I use.
THIS HAS CAUSED NETBEANS PROBLEMS AND THEY HAVE ACCEPTED A BUG ON THAT.
I am not at all sure this applies but it is mentioned for completeness.
The lack of mention on the web seemed to make this important but I do not think it is.

Log Files:
I looked in 
  C:\Users\gep\AppData\Roaming\OpenOffice\4\user
for some log files but did not see any.
Did not look further figuring you would tell me where they are and ask for them.

Configuration:
Ran cygwin's 
 "find . -type f |xargs grep localhost | grep -v Binary |less"
in the top level OpenOffice.org associated directories but that turned up too many hits to be of use.
