```

Objects will be evicted if the following conditions are met:
- The object has been idle longer than BaseGenericObjectPool.getMinEvictableIdleDuration() / BaseGenericObjectPool.getMinEvictableIdleDuration()
- There are more than GenericObjectPool.getMinIdle() / GenericKeyedObjectPoolConfig.getMinIdlePerKey() idle objects in the pool and the object has been idle for longer than BaseGenericObjectPool.getSoftMinEvictableIdleDuration() / BaseGenericObjectPool.getSoftMinEvictableIdleDuration()
This class is immutable and thread-safe.
