ExecutionContext

public class ExecutionContext extends Object
This class that implements ExecutionContext that gets stored in Thread Local Storage. If the current thread creates child threads, the context info that is stored in the current thread is automatically propogated to the child threads. Two class methods serve as a convinient way to set/get the Context information within the current thread. Thread Local Storage is a concept introduced in JDK1.2. So, it will not work on earlier releases of JDK.
