Hibernate does not recognize DBCP connection pool configurations from persistence.xml

Question

I want to use DBCP2 connection pooling from Apache commons in an SE environment: (build.gradle)

compile group: 'org.apache.commons', name: 'commons-dbcp2', version: '2.2.0'

persistence.xml:

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence
         http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd"
         version="2.1">

<persistence-unit name="MyPersistenceUnit" transaction-type="RESOURCE_LOCAL">
    <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
    <class>com.myapp.MyModel</class>
    <properties>
        <property name="javax.persistence.jdbc.driver" value="org.postgresql.Driver"/>
        <property name="javax.persistence.jdbc.url" value="jdbc:postgresql://localhost:5432/my_db"/>
        <property name="javax.persistence.jdbc.user" value="postgres"/>
        <property name="javax.persistence.jdbc.password" value="mypassword"/>

        <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQL94Dialect"/>
        <property name="hibernate.hbm2ddl.auto" value="validate"/>

        <property name="hibernate.dbcp.initialSize" value="5"/>
        <property name="hibernate.dbcp.maxTotal" value="20"/>
        <property name="hibernate.dbcp.maxIdle" value="10"/>
        <property name="hibernate.dbcp.minIdle" value="5"/>
        <property name="hibernate.dbcp.maxWaitMillis" value="-1"/>

        <property name="hibernate.show_sql" value="true"/>
        <property name="hibernate.format_sql" value="true"/>
    </properties>
</persistence-unit>

But Hibernate does not recognize this and still uses its built-in connection pooling:

WARN  org.hibernate.orm.connections.pooling - HHH10001002: Using Hibernate built-in connection pool (not for production use!)

Like coladict mentioned in his comment,

Hibernate does not support automatic configuration for Apache commons dbcp2.

It supports

C3P0, Proxool and Hikari. They are checked in that order.
