      Description

      I'm trying to implement REST API for Dynamic configuration. But NullPointerException occurred when ResourceOption.getOverCommitTimeout() called. Here is a sample code with error message.

      @Test
      public void testGetOverCommitTimeout() {
        Resource capability = Resource.newInstance(4096, 4);
        ResourceOption resourceOption = ResourceOption.newInstance(capability,
          RMNode.OVER_COMMIT_TIMEOUT_MILLIS_DEFAULT);
        Assert.assertEquals(RMNode.OVER_COMMIT_TIMEOUT_MILLIS_DEFAULT,
          resourceOption.getOverCommitTimeout());
      }
      
      java.lang.NullPointerException
