I'm trying to implement JBJCA-634 and hit an issue.
Support query timeout for check-valid-connection-sql
https://issues.jboss.org/browse/JBJCA-634
When I configured valid-connection-checker with NullValidConnectionChecker for testing purpose, I got this exception:
12:01:35,859 WARN [org.jboss.jca.adapters.jdbc.local.LocalManagedConnectionFactory] (JBossConnectionValidator) Exception trying to create connection checker (disabling):: java.lang.ClassNotFoundException: org.jboss.jca.adapters.jdbc.extensions.novendor.NullValidConnectionChecker from [Module "org.jboss.ironjacamar.impl:main" from local module loader @12b7eea (roots: /home/nekop/usr/src/as7/build/target/jboss-as-7.1.0.Alpha1-SNAPSHOT/modules)]

And here is my datasource config:
<datasource jndi-name="java:jboss/datasources/ExampleDS" enabled="true" use-java-context="true" pool-name="H2DS" spy="true">
<connection-url>jdbc:h2:mem:test;DB_CLOSE_DELAY=-1</connection-url>
<driver>h2</driver>
<pool>
<min-pool-size>2</min-pool-size>
<max-pool-size>10</max-pool-size>
<prefill>true</prefill>
</pool>
<security>
<user-name>sa</user-name>
<password>sa</password>
</security>
<validation>
<valid-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.novendor.NullValidConnectionChecker"/>
<!--
<valid-connection-checker class-name="org.jboss.jca.adapters.jdbc.CheckValidConnectionSQL">

<background-validation>true</background-validation>

</validation>

</datasource>
I've tested this with both AS7 Final and AS7 upstream and got same result.
Is this a config issue or a known bug?
