A "work-around" of sorts seems to be to not use a datasource. But that's bad
practice, I can get away with it because my application doesn't take heavy
traffic. But if I don't use a jta datasource and just connect to the
database directly then it works fine.

So

  <property name="openjpa.ConnectionURL"
       value="jdbc:oracle:thin:@(protected)" />
  <property name="openjpa.ConnectionDriverName"
value="oracle.jdbc.driver.OracleDriver" />
  <property name="openjpa.ConnectionUserName" value="user" />
  <property name="openjpa.ConnectionPassword" value="pass" />
</properties>

instead of
<provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
<properties>
   <property name="openjpa.DataCache" value="true"/>
   <property name="openjpa.RemoteCommitProvider" value="sjvm"/>
   <property name="openjpa.Log" value="DefaultLevel=WARN, Tool=INFO"/>
   <property name="openjpa.TransactionMode" value="managed"/>
</properties>
