"Oracle Support" is a link that goes to
this page. There is no email address there, but there are a few phone numbers.
This page has even more numbers, but it does suggest that you must have paid to get support. If you haven't you will probably have to wait until version 1.3.45 is made publicly available. Unless your code needs support for Ukraine, Moldavia, Brazil, Cuba or Fiji there isn't any reason why you can't wait.
