XML config - Unknown property - ManagementCoordinator

[niaouli]

Hi,
I red that the JMX management can be disable by setting the ManageCoordinator to NullManagementCoordinator. So I wrote this simple c3p0-config.xml file :

<?xml version="1.0" encoding="UTF-8"?>
<c3p0-config>
        <default-config>
                <!-- Disable JMX management -->
                <property name="com.mchange.v2.c3p0.management.ManagementCoordinator">com.mchange.v2.c3p0.management.NullManagementCoordinator</property>
        </default-config>
</c3p0-config>

But now I get this error :

WARN (com.mchange.v2.c3p0.cfg.C3P0Config) Unknown c3p0-config property: com.mchange.v2.c3p0.management.ManagementCoordinator

So is it a bug or is it my mistake? Thanks.
