------------------------------------------------------------
Ah, yes, the ctor... please try the attached patch [^commons-pool-gg.patch]
In the 2.x version, we have to keep backward compatibility in mind. This patch
will use the class name only if the class name is different from the default
class name.

> Version 2.4.3 GenericObjectPool constructor throws this exception:
> {{java.lang.IllegalArgumentException:
> [org.apache.commons.pool2.impl.DefaultEvictionPolicy] does not implement
> EvictionPolicy}}
> {{ at
> org.apache.commons.pool2.impl.BaseGenericObjectPool.setEvictionPolicyClassName(BaseGenericObjectPool.java:618)}}
