The program violates the Enterprise JavaBeans (EJB)
					specification by using thread synchronization primitives.The Enterprise JavaBeans specification requires that every bean provider
						follow a set of programming guidelines designed to ensure that the bean will
						be portable and behave consistently in any EJB container. In this case, the
						program violates the following EJB guideline: "An enterprise bean must not
						use thread synchronization primitives to synchronize execution of multiple
						instances." The specification justifies this requirement in the following
						way: "This rule is required to ensure consistent runtime semantics because
						while some EJB containers may use a single JVM to execute all enterprise
						bean's instances, others may distribute the instances across multiple
						JVMs."
