Investigate impact of self-attach flag requirement on plugins

XMLWordPrintable

      According to the information from evernat in JENKINS-52092, Monitoring Plugin 1.73.0 requires "-Djdk.attach.allowAttachSelf=true" to be set on master and agent side in order to have the memory histogram in JDK 9. (Edit: with an enhancement in the monitoring plugin 1.73.1, it does not attach itself to the VM in order to get heap histogram in JDK 9. So this plugin does not require to add "-Djdk.attach.allowAttachSelf=true".)

      We still have some plugins attaching to JDK (e.g. File Leak detector plugin), so maybe we need a generic solution for Jenkins packaging (or some documentation about "-Djdk.attach.allowAttachSelf=true").

          Description Original: According to the information from [~evernat] in JENKINS-52092, Monitoring Plugin requires "-Djdk.attach.allowAttachSelf=true" to be set on master and agent side in order to have the memory histogram in JDK 9.

          We have other plugins attaching to JDK (e.g. File Leak detector plugin), so maybe we need a generic solution for Jenkins packaging (or some documentation).
