      Description

      I get an NPE on updatehostdb. I start with a clean crawlDB & hostDB. After an inject, I do an updatehostdb with -checkAll and get the following stacktrace:

      2018-06-13 10:45:21,958 WARN hostdb.ResolverThread - java.lang.NullPointerException

      Is this related to NUTCH-2375?

      If further testing is needed, please let me know!
