I think I am, I wrote that code :). Code of the getConnectionCount():

public int getConnectionCount() {
return getPool().getFreeSize();
}

There's javadoc for getFreeSize(). When you start your application,
number of free connections in the pool is 5. Then if you take one
connection, it will be 4. It is strange that number of connectios
decreeses. If you are sure that there's no code "eating" the
connections, it can also be a bug in pool, when it releases idle
connections even below minPoolSize margin. I will check it too.
