> The following test demonstrates that finally block becomes unreachable on Jitrino/JET when while(true) loop is used in try statement.
> VM hangs. 
> On Jitrino/OPT and interpreter this test finishes successfully
> --------------------
> public class testFinally {
>     public static boolean started= false;
>     public static void main(String[] args) throws Exception {
>         Thread t  = new Thread(new TT());
>         t.start();
>         while(!started){
>         }
>         t.stop();
>         System.err.println("Thread.stop()");
>     }
>     static class TT implements Runnable {    
>         public void run() {
>             started = true;
>             try{
>                 synchronized(this) {
>                     while (true){
>                     }
>                 }
>             } finally {
>                 System.err.println("PASSED: thread was interrupted ");
>             }
>         }
>     }
> }
> ---------------------
> VM reports  "Thread.stop()" and gangs.
> On Jitrino/OPT output is:
> Thread.stop() 
> PASSED: thread was interrupted
