Hi guys

the singleton solution will not work, since several nodes
are possible in the cluster, each node has it's own java.
Those singleton can be instanciated in each class.

Beside this the presented implementation of singleton design
pattern is improper. You should override constructor in this
way :
private Singleton(){};

I also would make getInstance() method synchronized. This is
multithreaded environment.
