in case of  setting the  "timeBetweenEvictionRunsMillis",

when validationQuery is error, connection pool increase keep going.
Even if you set the maximum value(maxActive).

1. setting
    <Resource
         name="jdbc/PPAS_DS"
         type="javax.sql.DataSource"
         minIdle="2"
         initialSize="3"
         maxActive="6"
         timeBetweenEvictionRunsMillis="20000"

         username="xxx"
         validationQuery="select1 12 "
         driverClassName="org.postgresql.Driver"
         password="xxx"
         url="jdbc:postgresql://localhost:5432/postgres"/>

2. try to ues connection Pool
--> validationQuery error 
-------------------------------------------------------
3. server connection increases after 20000 Millis (timeBetweenEvictionRunsMillis value)
netstat -nap | grep 5432 | grep EST | grep java | wc -l
6
 netstat -nap | grep 5432 | grep EST | grep java | wc -l
8
-------------------------------------------------------
If Pool can not guarantee maxActive value, that is problem.

Did I  something wrong use timeBetweenEvictionRunsMillis option?

timeBetweenEvictionRunsMillis option is not available?
