Search fails without Glimpse #38

Closed Akron closed 6 years ago

Akron commented 6 years ago

As reported by Verginica, sometimes queries return no results (without any reported error), when Glimpse is deaktivated.

Provided example queries for the DRuKoLa instance: 

[drukola/m!="msd:ts.*"][drukola/m="msd:nc..o.*"][drukola/m="msd:nc..rn.*"]
[drukola/m="msd:nc..o.*"][drukola/m!="msd:s.*"][drukola/m="msd:nc..rn.*"]

I think this involves two errors:

  1. Problem with error reporting in Kalamar
  2. Problem with snippet generation in Krill

The reported error is


The RuntimeException could not be mapped to a response, re-throwing to the HTTP container
java.lang.NullPointerException
