FAQ

Q: If I have multiple threads calling into my method which contains the borrowObject call, do I have to synchronize around this, or are borrowObject and returnObject thread safe?
A: They appear to be thread safe. I haven't extensively studied the source the relevant code is synchronized.
Q: What is the general purpose of pooling Interfaces ?
A: ''You don't pool interfaces but objects implementing the interfaces. An object pool is used to reduce the cost of creating/destroying the pooled object (memory,CPU and other resources). Commons-Pool provides several general purpose implementations of different pooling strategies. See also [http://jakarta.apache.org/commons/pool/guide/index.html developers guide].
