Looking for a sponsor to review changes made to two unit tests under jdk/test (original) (raw)

We initially introduced CountdownLatch and now Semaphore, to replace the Thread.sleep(10) which took place before - what appears to be a forced GC (am I right?):

         System.err.println("GC " + i);
         System.gc();
         System.runFinalization();

As the threads join at the ends of the other, then we can do away with the Semaphore but how would we simulate the 10ms pause before the forced GC - is that necessary? Can we still use Semaphores to implement pauses?

Cheers, mani

Hi David,

Here's the version of *jdk8tl/jdk/**test/java/lang/*ref/Basic.javaimplemented using a Semaphore: Hi Mani, Is there a handshake really needed here? From a quick look at the test then it looks to me that fork (used by createNoise) does a Thread.join so it waiting until the task is complete before it returns. -Alan
