http://tomcat.apache.org/tomcat-6.0-doc/jndi-resources-howto.html 

In this Tomcat 6.x documentation page, it is stated that :

timeBetweenEvictionRunsMillis - The number of milliseconds between consecutive runs of the evictor. Default: 30*60*1000 (30 minutes)
minEvictableIdleTimeMillis - The idle time in milliseconds after which a connection can be removed from the pool by the evictor. Default: -1 (disabled)

The default values for those parameters are actually the other way around :

timeBetweenEvictionRunsMillis - The number of milliseconds between consecutive runs of the evictor. Default: -1 (disabled)
minEvictableIdleTimeMillis - The idle time in milliseconds after which a connection can be removed from the pool by the evictor. Default: 30*60*1000 (30 minutes)

You can see this on the GenericObjectPool class from commons-pool :

Thank you.
