We've had a l= ot of trouble lately because MySQL no longer seems to be properly enforcing= transaction integrity in at least some circumstances. OR it could be the = open-source MySQL driver we're using; maybe that needs an upgrade? At any rate, removal of jobqueue rows MUST precede removal of job table row= s; there's a constraint in place in fact. So if you get to the point where= that constraint has been violated, you're pretty certain it's a database i= ssue. :-( > [Set priority thread] Error tossed: null during startup > ------------------------------------------------------- > > Key: CONNECTORS-1581 > URL: https://issues.apache.org/jira/browse/CONNECTORS-158= 1 > Project: ManifoldCF > Issue Type: Bug > Environment: =E2=80=A2=09ManifoldCF 2.12, running in a Docker Con= tainer based on Redhat Linux, OpenJDK 8=20 > =E2=80=A2=09AWS RDS Database (Aurora MySQL -> 5.6 compatible, utf8 (colla= tion utf8_bin)) > =E2=80=A2=09Single Process Setup > Reporter: Markus Schuch > Assignee: Markus Schuch > Priority: Major > > We see the following {{NullPointerException}} at startup: > {code} > [Set priority thread] FATAL org.apache.manifoldcf.crawlerthreads- Error t= ossed: null > java.lang.NullPointerException > at org.apache.manifoldcf.crawler.system.ManifoldCF.writeDocumentPrioritie= s(ManifoldCF.java:1202) > at org.apache.manifoldcf.crawler.system.SetPriorityThread.run(SetPriority= Thread.java:141) > {code} > What could be the cause of that? -- This message was sent by Atlassian JIRA (v7.6.3#76005)
