Are empty loops with side effects in it's condition caught by dead code elimination?

Question

Given the following code

var cachedInt = new ArrayBlockingQueue<Integer>(xxxxx);

while(true){
   while(cachedInt.offer(randomProvider.nextInt()));
   latch.await();
}

Will the jvm eventually eliminate the while loop because it has no body or does it recognize the side effect of the condition and keep the loop in place?

empty loop? `while(true) {}` is not empty loop and it will run endlessly — ByeBye, Sep 12 '18 at 22:16
No the jvm will not "optimize" your method call away. Your condition will run repeatedly until it returns `false` and the side effects will happen as normal. — mypetlion, Sep 12 '18 at 22:36
