MySQL persistence broken after upgrade to latest OH2.2.0 snapshot

Hi!

I upgraded my Raspberry PI today to latest snapshot openHAB 2.2.0 Build #1066 via apt-get. My MySQL-persistence then stopped working, the openhab.log throws:

I’m running MySQL on the same RPI using the following mysql.cfg:

# the database url like 'jdbc:mysql://<host>:<port>/<database>' (without quotes)
url=jdbc:mysql://localhost:3306/OpenHAB

# the database user
user=openhab

# the database password
password=****

# the reconnection counter
#reconnectCnt=

# the connection timeout (in seconds)
#waitTimeout=

# Use MySQL Server time to store item values (=false) or use openHAB Server time (=true).
# For new installations, its recommend to set "localtime=true".
# (optional, defaults to false)
localtime=true

My mysql.persist:

// persistence strategies have a name and a definition and are referred to in the "Items" section
Strategies {
        // if no strategy is specified for an item entry below, the default list will be used
        everyMinute     : "0 * * * * ?"
        every5Minutes : "0 */5 * * * ?"
        everyHour   : "0 0 * * * ?"
        everyDay    : "0 0 0 * * ?"
        default = everyChange
}

Items {
    // persist all items once a day and on every change and restore them from the db at startup
    * : strategy = everyChange, everyDay, restoreOnStartup

    // additionally, persist all temperature and weather values every five minutes
    gTemp*, gHumid*, gRain*, gWind* : strategy = every5Minutes, restoreOnStartup
}

I’ve not installed the JDBC persistence, but it worked before today’s upgrade.

Any clues on what might be wrong?
