Sharing variable across Threads created by ThreadFactory

Question

Hi,
I am initializing an ExecutorService as:
static ExecutorService service =
Executors.newFixedThreadPool(16, new ThreadFactory() {
@Override
public Thread newThread(Runnable r) {
Thread t = new Thread(r);
t.setContextClassLoader("<<My_Class_Loader");
return t;
Now, I have to initialize a service that should be initialized only once that all the Callables submitted to this ExecutorService can use. The variable needed to be shared across the Threads must have "My_Class_Loader" as its ContextClassLoader. How can I do that? Thanks in advance.

Something like this:
Thread t = new MyThread(r, ccl); // ccl = your context class loader
public class MyThread extends Thread
  private MyVariable myVariable;
  public MyThread(Runnable r, ClassLoader ccl)
    super(r);
    this.setContextClassLoader(ccl);
    myVariable = ...; // your class loader stuff
  public MyVariable getMyVariable()
    return myVariable;
// ... then runnables can go:
((MyThread)Thread.currentThread()).getMyVariable();
