Why do they have to specify a default pool implementation?
Most likely all they want to do is change the pool size?

We should define defaults somewhere and reference them
from the three places that use.

e.g.

  | public interface PoolDefaults
  | {
  |     String defaultPool = "ThreadLocalPool";
  |     int defaultSize = 30;
  |     // etc.
  | }
  | public @interface Pool
  | {
  |     String value() default PoolDefaults.defaultPool;
  |     int size() default PoolDefaults.defaultSize;
  |     // etc.
  | }
  | 
  | public class PoolImpl implements Pool
  | {
  |    public String value = PoolDefaults.defaultPool;
  |    public int maxSize = PoolDefaults.defaultSize;
  |     // etc.
  | }
  |
