[xwiki-users] database related issue while upgrading to the brand new 7.0 release

Hi all! We have successfuly updated our XWiki 6.x installation along the whole 6 cycle, but I'm in troubles with the new 7.0 release. I think that with only the first four lines of the error stack XWiki initialization failed ! Exception thrown during job execution class java.lang.AbstractMethodError: null at org.apache.commons.dbcp2.DelegatingConnection.isValid(DelegatingConnection.java:914) at org.apache.commons.dbcp2.DelegatingConnection.isValid(DelegatingConnection.java:914) ...

As they are a lot of versions between mysql-connector-java-5.0.8-bin.jar (working for us nicely so far) and the newest mysql-connector-java-5.1.35-bin.jar (failing for us, at least with this combination of Java, Tomcat and MySQL), please, could you tell us if we are in the right direction? Should we update any other component but mysql-connector-java-x.y.z-bin.jar to get XWiki 7.0 working? Should we start trying one by one mysql-connector-java-x.y.z-bin.jar newer releases? Do you know which release introduces JDBC 4.1 support? Thanks you so much for your help!
