try-with-resources testing with PowerMockito under static method

I will very much appreciate if I get any answer regarding my problem with static method test which holds try-with-resources part of code.

Static method:

<pre>  

public class PropertiesUtil {

   public static Properties getProperties() {   
          Properties p = new Properties();        
          File configFile = new File("fileName");

                       <b>try (FileReader pFile = new FileReader(configFile)) {</b>
                              p.load(pFile);
                       } catch (IOException e) {
                              e.printStackTrace();
                       }
          return p;
   }

}

And when I run my test, run-with-resources block makes testing impossible:

<pre>

@Test public void testStatic() {

          PowerMockito.mockStatic(PropertiesUtil.class);
          PowerMockito.when(PropertiesUtil.getProperties()).thenReturn(new Properties());

... } I get failure trace:

How can I test this with PowerMockito??? Thank you in advance!
