MonitorAdmin - NullPointerException while calling MonitoringJob.stop() -----------------------------------------------------------------------
Key: FELIX-810 URL: https://issues.apache.org/jira/browse/FELIX-810 Project: Felix Issue Type: Bug Components: Sandbox Reporter: Martin Thelian I've started a scheduled job with: |> this.monitorService.startScheduledJob( |> PID, // listener.id |> variableNames.toArray(new String[variableNames.size()]), |> 60, // seconds |> 0 // Forever |> ); If I then need to stop the job via |> this.currentMonitorJob.stop(); e.g. because the variableName list has changed I'm getting the following NullpointerException: ----- |> java.lang.NullPointerException |> at org.apache.felix.sandbox.monitor.MonitorAdminImpl$MonitoringJobImpl.unsubscribeStatusVariables(MonitorAdminImpl.java:185) |> at org.apache.felix.sandbox.monitor.MonitorAdminImpl$MonitoringJobImpl.stop(MonitorAdminImpl.java:162) ----- The problem seems to be that there are no subscriptions in a scheduled job and therefore the variable "list" shown in the code fragment below is null. |> private void unsubscribeStatusVariables() { |> [...] |> List list=(List)subscriptions.get(statusVariableName); |> if(list!=null) { |> list.remove(this); |> } // else never occurs |> if(list.isEmpty()) |> subscriptions.remove(statusVariableName); |> } |> } -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
