Description

We see the following NullPointerException at startup:

[Set priority thread] FATAL org.apache.manifoldcf.crawlerthreads- Error tossed: null
java.lang.NullPointerException
at org.apache.manifoldcf.crawler.system.ManifoldCF.writeDocumentPriorities(ManifoldCF.java:1202)
at org.apache.manifoldcf.crawler.system.SetPriorityThread.run(SetPriorityThread.java:141)

What could be the cause of that?
