Title: Message Title

Spencer Small created an issue   Jenkins / JENKINS-51030 readYaml parses numerical strings as Double.Infinity Issue Type: Bug Assignee: Unassigned Components: core Created: 2018-04-26 18:50 Environment:  Jenkins 2.107.2, Linux Priority: Minor Reporter: Spencer Small I have the following YAML: Unable to find source-code formatter for language: yaml. Available languages are: actionscript, html, java, _javascript_, none, sql, xhtml, xml 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: Unable to find source-code formatter for language: groovy. Available languages are: actionscript, html, java, _javascript_, none, sql, xhtml, xml 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.
