bug for DBPoolDataSource set minpool size

[weiransoft]

public synchronized void setMinPool(int minPool)
{
this.maxPool = minPool;
if (pool != null)
pool.setParameters(this.minPool, pool.getMaxPool(), pool.getMaxSize(), pool.getIdleTimeout());
}

this.maxPool = minPool;
correct is ：
this.minPool = minPool;

Thanks for the feedback. I've just fixed this bug, and published v7.0.1 to Maven and main download site.
