      Description

      MetricsDynamicMBeanBase.java

      @Override
      public AttributeList getAttributes(String[] attributeNames) {
      if (attributeNames == null || attributeNames.length == 0)
      throw new IllegalArgumentException();

      The second clause isn't necessary.

      There's some code used by management software (RHQ) that occasionally will query with an empty list.

      Here is the stack trace.
