hibernate.statistics.query_max_size defaults the maximum number of queries to 5000 unless an application specifies a persistence unit hint property for "hibernate.statistics.query_max_size". This is to default WildFly to a lower max number of queries unless applications specify a different value in their persistence unit definition. The WildFly configured default will be 200 which is neither a large or small limit on the number of queries.

Applications can configure a different max queries setting if desired:

 <persistence-unit name="example_PU">
    ...
    <properties>
        <property name="hibernate.statistics.query_max_size" value="500" />
    </properties>
  </persistence-unit>
