1. The call to ConnectionPool.borrowConnection( ) is caused by setting
<property name="initialSize" value="5"/>
which causes ConnectionPool.init() to create 5 connections.
2. The call to PooledConnection.connectUsingDataSource() is seriously wrong.
It should have called PooledConnection.connectUsingDriver() instead.
This can happen only if poolProperties.getDataSource() is not null.
I do not see how this could have happened. Did Spring injected a recursive
reference by calling DataSource.setDataSource()?
3. When you define the pool via <Resource>, it is created using
org.apache.tomcat.jdbc.pool.DataSourceFactory. The factory calls
dataSource.createPool().
So it might be better to add init-method="createPool".
