According to Hibernate's documentation:

____
Hibernate's own connection pooling algorithm is, ... quite rudimentary. It is intended to help you get started and is _not intended for use in a production system_, or even for performance testing. You should use a third party pool for best performance and stability.
____


This rule raises an issue when a ``++hibernate.connection.pool_size++`` value is found in a _hibernate.cfg.xml_ or _hibernate.properties_ file.


== Noncompliant Code Example

----
<hibernate-configuration>
  <session-factory>
    <!-- ... -->
    <property name="connection.pool_size">10</property>  <!-- Noncompliant -->
  </session-factory>
</hibernate-configuration>
----
or 

----
// ...
hibernate.connection.pool_size=10  // Noncompliant
----
