[JIRA] [core] (JENKINS-21207) Invalid XML character in RESTful API output.

[senko....@gmail.com (JIRA)]

Jakub Senko created JENKINS-21207 Invalid XML character in RESTful API output. Issue Type: Bug Assignee: Unassigned Components: core Created: 03/Jan/14 12:32 AM Description: I was building a maven project (jenkins 1.544 actually) and one of the tests printed an invalid XML characted to stdout. This causes Jenkins to work with malformed XML document when the relevant output is accessed via API. When visiting following url: http://localhost:8080/job/jenkins/1/org.jenkins-ci.main$jenkins-test-harness/testReport/api/xml browser shows "XML Parsing Error: not well-formed" error. And if I try to filter the XML via xpath parameter: http://localhost:8080/job/jenkins/1/org.jenkins-ci.main$jenkins-test-harness/testReport/api/xml?xpath=//fooo Following exception is thrown ("Oops!" page): java.io.IOException: Failed to do XPath/wrapper handling. Turn on FINER logging to view XML. at hudson.model.Api.doXml(Api.java:154) at sun.reflect.GeneratedMethodAccessor235.invoke(Unknown Source) at
