Compliant Solution (thread)

In this compliant solution, even though the thread is created in the constructor, it is not started until its {{start()}} method is called from method {{startThread()}} \[[Goetz 02 |

class ThreadStarter implements Runnable {

It is safe to create the thread in the constructor as long as it is not started until object construction is over. This is because "A call to start() on a thread happens-before any actions in the started thread." \[[JLS 05|AA. Java References#JLS 05]\]. |
Risk Assessment
Allowing the this reference to escape may result in improper initialization and runtime exceptions.
