Configurar pool de beans no wildfly 14

Pessoal, vi que no jbossAS a configuração de pool do standalone.xml é realizada da seguinte forma:

Observem o argumento: max-pool-size="20"

<strict-max-pool name="slsb-strict-max-pool" max-pool-size="20" 
        instance-acquisition-timeout="5" instance-acquisition-timeout-unit="MINUTES"/>

Toda via estou utilizando wildfy 14 e não consta argumento: max-pool-size="20" na tag conforme fonte abaixo.

<strict-max-pool name="mdb-strict-max-pool" derive-size="from-cpu-count" instance-acquisition-timeout="5" instance-acquisition-timeout-unit="MINUTES"/>

Quando fui adicionar o argumento: max-pool-size="20" no standalone.xml

<strict-max-pool name="mdb-strict-max-pool" max-pool-size="20" derive-size="from-cpu-count" instance-acquisition-timeout="5" instance-acquisition-timeout-unit="MINUTES"/>

O wildfly iniciou com o seguinte erro:

OPVDX001: erro de validação em standalone.xml ----------------------------------

Poderiam me auxiliar? Obrigado!
