So, if I have this class in the classpath twice (in two different jars) would also cause the same issue, correct ?
I will take a look into the classloader/classpath issues. One thing I am not sure though why I see this issue sporadically, but not consistently ?...

Hi Gul, The root cause is class path or class loader problems. A class loaded by a different class loader is considered to be a different class by Java even if it has the same name. Does this help?
