----------------------------------------

             Summary: In case of using ArrayBlockingQueue as key, cache.get() returns null.
                 Key: IGNITE-12315
                 URL: https://issues.apache.org/jira/browse/IGNITE-12315
             Project: Ignite
          Issue Type: Bug
            Reporter: Alexander Lapin


In case of using ArrayBlockingQueue as key, cache.get() returns null. In case of using ArrayList
or LinkedList everything works as expected.
{code:java}
ArrayBlockingQueue<Integer> queueToCheck = new ArrayBlockingQueue<>(5);
queueToCheck.addAll(Arrays.asList(1, 2, 3));

cache.put(queueToCheck, "aaa");
cache.put(queueToCheck); // returns null
{code}
