Management console is showing "Statistics Disabled" for Datasources

Issue

• Management console is showing Statistics Disabled when using system properties values instead of fixed value (statistics-enabled="true")

For example Using :

<datasource jndi-name="java:jboss/datasources/ExampleDS" pool-name="ExampleDS" enabled="true" use-java-context="true" statistics-enabled="${wildfly.datasources.statistics-enabled:${wildfly.statistics-enabled:true}}">

Instead of fixed value:

<datasource jndi-name="java:jboss/datasources/ExampleDS" pool-name="ExampleDS" enabled="true" use-java-context="true" statistics-enabled="true">
