DurableTaskStep$Execution.getStatus can hang

XMLWordPrintable

      There is some improvements to be made in the support core plugin (will create a different jira), but there is a case where the pipeline step executions toString method can hang forever if it is unable to obtain the durable task steps workspace:

      "Running CpsFlowExecution[Owner[JOB_NAME:JOB_NAME#BUILD_NUMBER]] / waiting for hudson.remoting.Channel@111111111:NODE_NAME" #1 daemon prio=5 os_prio=0 tid=0x000000002e00d800 nid=0x4a8 in Object.wait() [0x000000002f5de000]

      I believe the issue is that the StepExecution.toString make a call to getStatus which if it is currently in a DurableTaskStep.getStatus method call it will try to get the workspace which could potentially hang if something has happened to the channel.
