In the code, tx.commit() is not reached. Is there a way to rollback the
cache.put("test1", "1"); cache.put("test2", "2");

        
            public IgniteTest() {
		CacheConfiguration cacheCfg = new CacheConfiguration();
		cacheCfg.setName("cacheName");
		cacheCfg.setAtomicityMode(CacheAtomicityMode.TRANSACTIONAL);

		IgniteConfiguration cfg = new IgniteConfiguration();
		cfg.setCacheConfiguration(cacheCfg);
		
		TransactionConfiguration txCfg = new TransactionConfiguration();
		cfg.setTransactionConfiguration(txCfg);
		
		cfg.setClientMode(true);
		Ignite ignite = Ignition.start(cfg);
		transactions = ignite.transactions();
		cache = ignite.getOrCreateCache("txn test cache");
	}
	
	public void run() {
		Transaction tx = transactions.txStart(TransactionConcurrency.OPTIMISTIC,
                TransactionIsolation.SERIALIZABLE);
		try{
			  
		    cache.put("test1", "1");
		    cache.put("test2", "2");
		    
		    String[] bug = null;
		    bug[0] = "hello";
		    
		    cache.put("test3", "3");
		    System.out.println("tx.commit");
		    tx.commit();
		}catch (Exception ex) {
			ex.printStackTrace();
			System.out.println("tx.rollback");
			tx.rollback();
		}
	}
