--------------------------------------

             Summary: Better handling for Double.NaN
                 Key: SLING-5549
                 URL: https://issues.apache.org/jira/browse/SLING-5549
             Project: Sling
          Issue Type: Improvement
          Components: Extensions
            Reporter: Chetan Mehrotra
            Priority: Minor
             Fix For: JMX Resource Provider 1.0.4, Commons JSON 2.0.18


Its possible that some JMX attribute results in Double.NaN which causes issue with JSON rendition

As a fix we should
# Skip such properties in JSON renderer
# Skip such attributes in JMX Resource ValueMap
