Occurred in https://github.com/jenkinsci/jenkins/pull/5425 which probably changed the order of test execution in https://github.com/jenkinsci/jenkins/blob/master/test/src/test/java/hudson/cli/GetNodeCommandTest.java

Some tests grant Computer.EXTENDED_READ permission. If they run before getNodeShouldFailWithoutComputerReadPermission (wrong name), the error message references that permission rather than Agent/Configure.
