There are many database connection pool implementation available for java, for example; commons-dbcp , commons-dbcp2 ( newer version) , Hikari cp , tomcat jdbc connection pool and c3p0. Wildfly lets the application to be configured the connection pool in the datasource ( in the standalone*.xml ) files. But wondering does Wildfly uses any of the connection pool implementations ?

Wildfly uses iron jacamar version 1.2.4 which is an implementation of the Java EE JCA specification. All binaries are located in the module /org/jboss/ironjacamar. JCA is used to connect different kind of enterprise system in your application server (Message Broker, SAP, etc..) not only RDB.
