Infinite waiting in loop

{noformat}
        for (int attempt = 0;; attempt++) {
            if (attempt != 0) {
                try {
                    Thread.sleep(attempt * 10); // Wait for exchange.
                }
                catch (InterruptedException e) {
                    Thread.currentThread().interrupt();

                    throw new CacheException("Query was interrupted.", e);
                }
            }
{noformat}

because of exchange will wait for partition eviction with opened transaction in a related thread
