Florin the error you have pasted isn’t ringing a bell for me but when I first tried the upgrade last week I too had some errors when I restarted tomcat.  What I learned was in addition to redeploying with the new war file, I had to run the postgres update script and delete the previous ldap connector.  

It’s is described a bit here:

Once I performed those steps everything was fine again.  

Hope this helps.
