           Summary: GenericObjectPool is a LIFO, not a FIFO implementation
           Product: Commons
           Version: 1.2 Final
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Pool

        ReportedBy: thomas@schuerger.com


Hi,

the GenericObjectPool implementation is (like the StackedObjectPool) a LIFO, not
a FIFO implementation  as stated here:
http://jakarta.apache.org/commons/pool/guide/index.html).

When borrowObject() is called, the first available object is extracted from the
pool using removeFirst(). When returnObject(obj) is called, the object is
returned to the pool using addFirst(). I would expect that addLast() is used if
this is supposed to be a FIFO implementation.

But perhaps the developers guide is wrong, not the implementation.
