Subject [jira] [Updated] (OAK-2731) NPE when calling Event.getInfo()
Date Mon, 01 Jun 2015 15:49:18 GMT

     [ https://issues.apache.org/jira/browse/OAK-2731?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Francesco Mari updated OAK-2731:
    Attachment: ObservationBusyTest.java

I tried to reproduce the issue with the attached {{ObservationBusyTest}}. Since the issue
occurred during a reordering event ({{EventFactory$7.getInfo}}) on a very busy system, my
first attempt is to generate a lot of reordering events while a listener is observing. I also
supposed that the error was observed on a system using TAR persistence.

In my case, the system failed with an {{IllegalStateException}}, but I was unable to reproduce
the reported issue neither on 1.1.6 nor on the latest trunk. [~marett], [~dpfister], can you
verify if the attached test case is close to the real load on your system?
