What could be the possibilities of using a thread-unsafe java.sql.Connection object in java?

Everything can happen here. Note that obj_ClsPreparedStmt is a member variable whereas it's used as a local variable - it seems to be a much more serious problem than shared Connection .

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
