JBoss EAP 5.2.0 is unable to resolve pingDatabase method

Issue

Our Oracle datasource is setup with connection checking and worked fine in JBoss EAP 5.1.x

    <valid-connection-checker-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleValidConnectionChecker</valid-connection-checker-class-name>

We have upgraded to JBoss EAP 5.2.0 and are now seeing a failure in the logs:

... WARN  [org.jboss.resource.adapter.jdbc.local.LocalManagedConnectionFactory] (WorkerThread#3[10.10.10.10:12345]:) Exception trying to create connection checker (disabling):
org.jboss.util.NestedRuntimeException: Unable to resolve pingDatabase method:; - nested throwable: (java.lang.NoSuchMethodException: oracle.jdbc.OracleConnection.pingDatabase())
        at org.jboss.resource.adapter.jdbc.vendor.OracleValidConnectionChecker.<init>(OracleValidConnectionChecker.java:62)

and below:

Caused by: java.lang.NoSuchMethodException: oracle.jdbc.OracleConnection.pingDatabase()
        at java.lang.Class.getMethod(Class.java:1605)
        at org.jboss.resource.adapter.jdbc.vendor.OracleValidConnectionChecker.initPing(OracleValidConnectionChecker.java:93)
        at org.jboss.resource.adapter.jdbc.vendor.OracleValidConnectionChecker.<init>(OracleValidConnectionChecker.java:58)
        ... 86 more

We do not see this message with JBoss EAP 5.1.2. How can it be fixed with JBoss EAP 5.2.0?
