    Description

      Follows up on CLOUD-1185

      jstat in a container built with the OpenJDK S2I Image does not work

      The problem seems to be specific to openjdk image, as it is not caused by the same problem as CLOUD-1185 (there is no hsperfdata_jboss as in the other cases)

      sh-4.2$ jps

          Enhancement - An enhancement to or refactoring of existing functionality that is not configurable by an end user (typically a change made by an internal team that affects users) CLOUD-2374 Update Red Hat OpenJDK S2I container image

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
