As @rgettman says, the name Predicate is unhappy... Anyways, you could take advantage of default methods in Java:

interface PredicateButPleaseChangeMyName {

    void test() throws InterruptedException;

    default void tryTest() {
       try {
          this.test();
       } catch (InterruptedException e) {
          // handle e (log or wrap in a RuntimeException)
       }
    }
}

Then, in your main method, simply create the threads by calling the default tryTest() method:

Thread t1 = new Thread(() -> prod.tryTest());
Thread t2 = new Thread(() -> cons.tryTest());
