```
public PoolUtils()
```
    PoolUtils instances should NOT be constructed in standard programming. Instead, the class should be used procedurally: PoolUtils.adapt(aPool);. This constructor is public to permit tools that require a JavaBean instance to operate.
- Method Detail
  - checkRethrow
```
public static void checkRethrow(Throwable t)
```
    Should the supplied Throwable be re-thrown (eg if it is an instance of one of the Throwables that should never be swallowed). Used by the pool error handling for operations that throw exceptions that normally need to be ignored.
    
    Parameters:
    t - The Throwable to check
    
    Throws:
    
    ThreadDeath - if that is passed in
    
    VirtualMachineError - if that is passed in

public static <T> ObjectPool<T> synchronizedPool(ObjectPool<T> pool)
```
    Returns a synchronized (thread-safe) ObjectPool backed by the specified ObjectPool.
    Note: This should not be used on pool implementations that already provide proper synchronization such as the pools provided in the Commons Pool library.

    Type Parameters:
    T - the type of object
    Parameters:
    pool - the ObjectPool to be "wrapped" in a synchronized ObjectPool.

    Returns a synchronized (thread-safe) KeyedObjectPool backed by the specified KeyedObjectPool.
    Note: This should not be used on pool implementations that already provide proper synchronization such as the pools provided in the Commons Pool library. Wrapping a pool that waits for poolable objects to be returned before allowing another one to be borrowed with another layer of synchronization will cause liveliness issues or a deadlock.
    
    Type Parameters:
    K - the type of key
    V - the type of object
    Parameters:
    keyedPool - the KeyedObjectPool to be "wrapped" in a synchronized KeyedObjectPool.

  - erodingPool
```
public static <T> ObjectPool<T> erodingPool(ObjectPool<T> pool)
```
    Returns a pool that adaptively decreases it's size when idle objects are no longer needed. This is intended as an always thread-safe alternative to using an idle object evictor provided by many pool implementations. This is also an effective way to shrink FIFO ordered pools that experience load spikes.
    
    Type Parameters:
    T - the type of object
    Parameters:
    pool - the ObjectPool to be decorated so it shrinks it's idle count when possible.
    
    Returns:
    a pool that adaptively decreases it's size when idle objects are no longer needed.
    Since:
    
    Pool 1.4

  - erodingPool
```
public static <T> ObjectPool<T> erodingPool(ObjectPool<T> pool,
                            float factor)
```
    Returns a pool that adaptively decreases it's size when idle objects are no longer needed. This is intended as an always thread-safe alternative to using an idle object evictor provided by many pool implementations. This is also an effective way to shrink FIFO ordered pools that experience load spikes.
    The factor parameter provides a mechanism to tweak the rate at which the pool tries to shrink it's size. Values between 0 and 1 cause the pool to try to shrink it's size more often. Values greater than 1 cause the pool to less frequently try to shrink it's size.
    
    Type Parameters:
    T - the type of object
    Parameters:
    pool - the ObjectPool to be decorated so it shrinks it's idle count when possible.
    factor - a positive value to scale the rate at which the pool tries to reduce it's size. If 0 < factor < 1 then the pool shrinks more aggressively. If 1 < factor then the pool shrinks less aggressively.
    
    Returns:
    a pool that adaptively decreases it's size when idle objects are no longer needed.
    Since:
    
    Pool 1.4

    erodingPool(ObjectPool)
  - erodingPool
```
public static <K,V> KeyedObjectPool<K,V> erodingPool(KeyedObjectPool<K,V> keyedPool)

This is intended as an always thread-safe alternative to using an idle object evictor provided by many pool implementations. This is also an effective way to shrink FIFO ordered pools that experience load spikes.
    
    Type Parameters:
    K - the type of key
    V - the type of object
    Parameters:
    keyedPool - the KeyedObjectPool to be decorated so it shrinks it's idle count when possible.
    
    Returns:
    a pool that adaptively decreases it's size when idle objects are no longer needed.

```
public static <K,V> KeyedObjectPool<K,V> erodingPool(KeyedObjectPool<K,V> keyedPool,
                                     float factor)
```
    Returns a pool that adaptively decreases it's size when idle objects are no longer needed. This is intended as an always thread-safe alternative to using an idle object evictor provided by many pool implementations. This is also an effective way to shrink FIFO ordered pools that experience load spikes.
    The factor parameter provides a mechanism to tweak the rate at which the pool tries to shrink it's size. Values between 0 and 1 cause the pool to try to shrink it's size more often. Values greater than 1 cause the pool to less frequently try to shrink it's size.
    
    Type Parameters:
    K - the type of key
    V - the type of object
    Parameters:
    keyedPool - the KeyedObjectPool to be decorated so it shrinks it's idle count when possible.
    factor - a positive value to scale the rate at which the pool tries to reduce it's size. If 0 < factor < 1 then the pool shrinks more aggressively. If 1 < factor then the pool shrinks less aggressively.
    
    Returns:
    a pool that adaptively decreases it's size when idle objects are no longer needed.

    Returns a pool that adaptively decreases it's size when idle objects are no longer needed.

This is also an effective way to shrink FIFO ordered pools that experience load spikes.
    The factor parameter provides a mechanism to tweak the rate at which the pool tries to shrink it's size. Values between 0 and 1 cause the pool to try to shrink it's size more often. Values greater than 1 cause the pool to less frequently try to shrink it's size.
    
    The perKey parameter determines if the pool shrinks on a whole pool basis or a per key basis. When perKey is false, the keys do not have an effect on the rate at which the pool tries to shrink it's size. When perKey is true, each key is shrunk independently.
    
    Type Parameters:
    K - the type of key
    V - the type of object
    Parameters:
    keyedPool - the KeyedObjectPool to be decorated so it shrinks it's idle count when possible.
    factor - a positive value to scale the rate at which the pool tries to reduce it's size. If 0 < factor < 1 then the pool shrinks more aggressively. If 1 < factor then the pool shrinks less aggressively.
    perKey - when true, each key is treated independently.
    
    Returns:
    a pool that adaptively decreases it's size when idle objects are no longer needed.
