title: InetAddress static method doesn't mock with PowerMockito
body: <p>I am running into weird problem while trying to mock static methods in InetAddress. I am successfully able to mock static methods for many of other classes and all works fine, but InetAddress showing different behavior. I am using JUnit 4.x, Mockito 1.9.5 &amp; PowerMock 1.5.6.</p>
  
  <p>Given below test using Mockito and PowerMock, and InetAddress mocking works fine -</p>
  
  <pre><code>@RunWith(PowerMockRunner.class)
  @PrepareForTest({InetAddress.class})
  public class UtilityTest {
  
      @Mock
      InetAddress inetAddress;
  
      @Test
      public void testGetCurrentHost() throws UnknownHostException {
          mockStatic(InetAddress.class);
          when(InetAddress.getLocalHost()).thenReturn(inetAddress);
          when(inetAddress.getHostAddress()).thenReturn("1.1.1.1");
          assertEquals("1.1.1.1", getCurrentHost());
      }
  
      private static String getCurrentHost() throws UnknownHostException {
          return InetAddress.getLocalHost().getHostAddress();
      }
  }
  </code></pre>
  
  <p>When I put the given below method in some utility, InetAddress.getLocalHost() doesn't mock anymore and test fails.</p>
  
  <p><strong>Move it to Utility :</strong></p>
  
  <pre><code>private static String getCurrentHost() throws UnknownHostException {
      return InetAddress.getLocalHost().getHostAddress();
  }
  </code></pre>
  
  <p><strong>Now my test looks like (and fails) :</strong></p>
  
  <pre><code>@RunWith(PowerMockRunner.class)
  @PrepareForTest({InetAddress.class})
  public class UtilityTest {
  
      @Mock
      InetAddress inetAddress;
  
      @Test
      public void testGetCurrentHost() throws UnknownHostException {
          mockStatic(InetAddress.class);
          when(InetAddress.getLocalHost()).thenReturn(inetAddress);
          when(inetAddress.getHostAddress()).thenReturn("1.1.1.1");
          assertEquals("1.1.1.1", Utility.getCurrentHost());
      }
  }
  </code></pre>
  
  <p>Given below is my stacktrace - </p>
  
  <pre><code>org.junit.ComparisonFailure: 
  Expected :1.1.1.1
  Actual   :192.111.111.121
