Issue

The datasoruce connection pool prefill feature does not work at the start-up in JBoss EAP 7.1.

I configured the following data source setting:

            <datasource jndi-name="java:jboss/datasources/ExampleDS" pool-name="ExampleDS" enabled="true" statistics-enabled="true">
                <connection-url>jdbc:postgresql://localhost:5432/example</connection-url>
                <driver>postgresql.jar</driver>
                <pool>
                    <min-pool-size>10</min-pool-size>
                    <max-pool-size>10</max-pool-size>
                    <prefill>true</prefill>
                </pool>
                <security>
                    <user-name>...</user-name>
                    <password>...</password>
                </security>
            </datasource>

with the above configuration, the connection pool is filled to <min-pool-size> at the start-up in EAP 7.0.x. However, the pool is filled at the start-up in EAP 7.1.x.
