[interim solution] Are there solutions for starting LO 4.1.2.3 without java on OSX 10.9 where OSX upgrade as been done on LO with JVM selected

No guarantees on this, and certainly no suggestions that it is an
elegant solution or the easiest....

Go in to your config directory and rename the file ~/Library/Application
Support/LibreOffice/4/user/config javasettings_MacOSX_x86.xml.
Now start LO
This time LO will open though it will prompt you for a JRE. Ignore the
message and go to Preferences->Advanced and unclick the use JVM switch.
You may also have to go to Extension Manager and disable your Grammar
checker as it appears that this extension instantiates immediately
crashing LO before you can change prefs.
Now you can probably use LO, though Zotero will not work (it will will
prompt you for a JRE and then crash LO)

– hopefully you can point LO towards a 64 bit java 1.7 install when LO
allows you to do that???)
