readYaml parses numerical strings as Double.Infinity

XMLWordPrintable

      I have the following YAML:

      this:
  is:
    a:
      string: "44e6696"

      I would expect that when I call readYaml in a Jenkins pipeline, the value of "44e6696" will be preserved as a String. Instead, it appears to be parsed as a Double and ends up with the value of Infinity:

      def yaml = readYaml(file: "myFile.yaml")
echo "Class info: ${yaml.this.is.a.string.getClass().dump()}"
echo "Value: ${yaml.this.is.a.string}"

      Class info: <java.lang.Class@78e67e0a cachedConstructor=null newInstanceCallerCache=null name=java.lang.Double reflectionData=java.lang.ref.SoftReference@2f922ce0 classRedefinedCount=0 genericInfo=sun.reflect.generics.repository.ClassRepository@51a80565 enumConstants=null enumConstantDirectory=null annotationData=null annotationType=null classValueMap=null>
Value: Infinity

      I have not been able to identify a workaround.

          Description Original: I have the following YAML:

          {code}

          I would expect that when I call {{readYaml}} in a Jenkins pipeline, the value of "44e6696" will be preserved as a String. Instead, it appears to be parsed as a Double and ends up with the value of {{Infinity}}:

          {code:groovy}
          def yaml = readYaml(file: "myFile.yaml")
          echo "Class info: ${yaml.this.is.a.string.getClass().dump()}"
          echo "Value: ${yaml.this.is.a.string}"
          {code}

          {code}
