fiber.get() in another fiber cause java.lang.NullPointerException

[tigerMoon]

the situation like this , in a fiber call another method,and in another method call fiber.get() method will cause this problem:

new Fiber<Void>((SuspendableRunnable) () -> {
            doSomething();
        }).inheritThreadLocals().start();

Then in the method use get() method:

@Suspendable
 doSomething(){
   // another fiber
    Fiber<R> fiber = new Fiber<R>() {
            @Override
            protected R run() throws SuspendExecution, InterruptedException {
                return companyTwoParam.apply(t1, t2);
            }
        };
        fiber.inheritThreadLocals();
        fiber.start();
        return fiber;

      fiber.get(); //  the problem is here
}

If i change the outside fiber to use thread ,it`s fine

Exception in Fiber "fiber-10000015" If this exception looks strange, perhaps you've forgotten to instrument a blocking method. Run your program with -Dco.paralleluniverse.fibers.verifyInstrumentation to catch the culprit!

I had use -Dco.paralleluniverse.fibers.verifyInstrumentation but there is no detect info,(it`s useful another situation)

In our product we use channel to transmit messages . but i also has some doubts about this.

doSomething is not marked suspendable (with with a @Suspendable annotation or with throws SuspendExecution).

I have marked it in my case , i will provide the exmaple project on github later . thank you

[tigerMoon]

than you pron . this is an invalid issue.
