Document

Timeout in seconds before an abandoned object can be removed.

The time of most recent use of an object is the maximum (latest) of TrackedUse#getLastUsed() (if this class of the object implements TrackedUse) and the time when the object was borrowed from the pool.

The default value is 300 seconds.
