Wildflyとデータベースへの自動再接続

これはWildfly8.1で動作します：

         <datasource jta="true" jndi-name="java:jboss/datasources/xxxdb" pool-name="xxxxDB" enabled="true" use-ccm="false">
          <connection-url>jdbc:mysql://localhost:3306/xxxdb?autoReconnect=true&amp;amp;useUnicode=true&amp;amp;characterEncoding=UTF-8</connection-url>
          <driver-class>com.mysql.jdbc.Driver</driver-class>
          <driver>mysql-connector-java-5.1.26-bin.jar</driver>
          <security>
              <user-name>xxxuser</user-name>
              <password>xxxpassword</password>
          </security>
          <validation>
              <check-valid-connection-sql>select 1</check-valid-connection-sql>
              <validate-on-match>false</validate-on-match>
              <background-validation>true</background-validation>
              <background-validation-millis>10000</background-validation-millis>
          </validation>
          <statement>
              <share-prepared-statements>false</share-prepared-statements>
          </statement>
        </datasource>
