    Description

      The readJSON step does not return any key named 'class'

      For example:

      input = '{"class":"example","other":"value"}'
echo "${input}"
output = readJSON text: input
echo "${output}"

      Returns:

      [Pipeline] Start of Pipeline
[Pipeline] echo
{"class":"example","other":"value"}
[Pipeline] readJSON
[Pipeline] echo
[other:value]
[Pipeline] End of Pipeline

      Is this a reserved keyword?

          Apparently this is because Jenkins uses a patched json-lib to remove "class", "declaringClass", and "metaClass" from json files.  See https://github.com/jenkinsci/json-lib/blob/16052d1f74908fb59430eddd73f42aec2469b313/src/main/java/net/sf/json/JsonConfig.java#L49.
