you should make it a Singleton (an object existing only once)
- write a private default Constructor (so you can't initiate an object by
Constructor)
- write a static method getInstance to get an object of the class; this
method creates an object, if it doesn't exist and stores the reference in a
class variable and returns this variable in every case

this approach controlls the usage of your pool objects; in your solution with
the static pool the garbage collector might throw away your pool
