polish error in example doc

[GoogleCodeExporter]

http://docs.google.com/View?docid=dd2fhx4z_5df5hw8
in this page in the counting example, the count instance var should be
volatile for the example to work.

@SessionScoped
public class Counter {

  volatile int count = 0;

  /** Increments the count and returns the new value. */
  public synchronized int increment() {
    return count++;
  }
}

the increment method is synchronized, so we're safe.

After A bit of re-reading the JLS, you are right. Sorry for the inconvenience.
