> The problem is originally reported by Mario: http://apache-ignite-users.70518.x6.nabble.com/Semaphore-blocking-on-tryAcquire-while-holding-a-cache-lock-td3031.html
> *Description*
> When a lock is held on a cache key, another node cannot join topology. It hangs somewhere on partition exchange future.
> *Steps to reproduce*
> Run the following code and observe that ">>> STARTED 2" is never printed because we cannot leave Ignition.start() method.
> {code}
> public static void main(String[] args) {
>     // Start the first node.
>     Ignite ignite = Ignition.start(new IgniteConfiguration().setGridName("1"));
>     System.out.println(">>> STARTED 1");
>     // Create cache and obtain a lock on it.
>     CacheConfiguration<String, String> ccfg =
>         new CacheConfiguration<String, String>().setAtomicityMode(CacheAtomicityMode.TRANSACTIONAL);
>     ignite.getOrCreateCache(ccfg).lock("key").lock();
>     System.out.println(">>> LOCKED");
>     Ignition.start(new IgniteConfiguration().setGridName("2"));
>     System.out.println(">>> STARTED 2");
> }
> {code}
