Description

I wrote some simple LinkedBlockingQueue test and it fails with the following exception when the Queue is actually not full.

Exception in thread “main” java.lang.IllegalStateException: Queue full at java.util.AbstractQueue.add(AbstractQueue.java:64) at com.tctest.concurrent.LinkedBlockingQueueTest.populateQueue(LinkedBlockingQueueTest.java:70) at com.tctest.concurrent.LinkedBlockingQueueTest.runTest(LinkedBlockingQueueTest.java:36) at com.tctest.concurrent.LinkedBlockingQueueTest.main(LinkedBlockingQueueTest.java:31)

The code is attached. One can run it using the accompanying script. Run as ./run.sh 2

It fails with the above exception once in a few runs. Note that the LinkedBlockingQueue was created with no bounds.

Fix the instrumentation. Add a LinkedBlockingQueuePerfTest.
