[dbcp]the activity when number of active connections reach (maxActive-minIdle)

[sum2000]

for example,pool size:
db.pool.size.init=5
db.pool.size.active.max=20
db.pool.size.idle.max=20
db.pool.size.idle.min=10
when # of active connections reach 10, what's the following activity of dbcp?
We know it can’t create new one for idle due to no availabe pool resource, if 
true dbcp can’t keep minIdle for 10, so what's next happen?


Thank you.
