It seems that the cobertura plugin version was upgraded recently in jenkins.
Since then, the Torque jenkins builds failed, the first failing build was https://builds.apache.org/view/S-Z/view/Torque/job/Torque4-trunk/332/console The root cause is java.io.NotSerializableException: hudson.plugins.cobertura.CoberturaPublisher It seems that the problem is described in https://issues.jenkins-ci.org/browse/JENKINS-15518 and that upgrading to the cobertura plugin version 1.7.1 would help. Could someone please check the cobertura plugin version(I'm afraid I have no idea how to do this myself) and, if the version is 1.6 or 1.7, upgrade to 1.7.1 ? Thanks in advance, Thomas
