Clear is leaking transaction with Batching

  public void testClearInBatch() {
      Cache<String, String> cache = createCache("testClearInBatch");
      cache.put("k2", "value2");

      cache.startBatch();
      cache.clear();
      cache.put("k1", "value1");
      cache.endBatch(true);

      // the tx is leaked and it tries to execute the get() against a committed transaction.
      AssertJUnit.assertEquals(null, cache.get("k2"));
      AssertJUnit.assertEquals("value1", cache.get("k1"));
   }
