Deadlock between lock and put under heavy concurrency
-----------------------------------------------------

                 Key: ISPN-373
                 URL: https://jira.jboss.org/jira/browse/ISPN-373
             Project: Infinispan
          Issue Type: Bug
          Components: Locking and Concurrency
    Affects Versions: 4.0.0.Final
         Environment: Mac OS-X 10.6, 2.8Ghz Core 2, 8GB RAM
            Reporter: Nigel Slack-Smith
            Assignee: Manik Surtani


Concurrent calls to lock and then put seem to be deadlocking. After AdvancedCache.lock is called under a transaction a subsequent call to Cache.put on the same key normally does not attempt to take out a lock, but after a variable number of concurrent calls Cache.put is attempting to take out a lock and then deadlocking with the AdvancedCache.lock call. 

Here's my test case which hits the deadlock.

public class DataGridTest {
	@Test
	public void testCreate() {
		CacheManager cacheManager = new DefaultCacheManager();
		final String cacheName = "TestCache";

		Configuration config = new Configuration();
		config.setTransactionManagerLookupClass("org.infinispan.transaction.lookup.DummyTransactionManagerLookup");

		cacheManager.defineConfiguration(cacheName, config);

		final Cache<Object, Object> cache = cacheManager.getCache(cacheName);
		cache.start();
		
		ExecutorService executorService = Executors.newFixedThreadPool(2);
		for (int i = 0; i < 1000000; ++i) {
			final String valueStr = "V" + i;
			
			executorService.execute(new Runnable() {
				@Override
				public void run() {
					TransactionManager txnMgr = cache.getAdvancedCache().getTransactionManager();
					
					try {
						txnMgr.begin();
					} catch (Exception e) {
						fail(e.getMessage());
					}
					
					cache.getAdvancedCache().lock("K1");
					cache.put("K1", valueStr);
					
					try {
						txnMgr.commit();
					} catch (Exception e) {
						fail(e.getMessage());
					}
				}
			});
		}

		executorService.shutdown();
		try {
			if (executorService.awaitTermination(300, TimeUnit.SECONDS) == false) {
				fail("Termination timeout");
			}
		} catch (InterruptedException e) {
			fail("Thread interrupted exception: " + e.getMessage());
		}
	}
}

...and here's the stack trace showing what appears to be a deadlock timeout.
