From 4f2e01ce0175434240f523e9722f1cd236c7afde Mon Sep 17 00:00:00 2001 From: Michal Kabaj Date: Mon, 13 Aug 2018 12:21:07 +0200 Subject: Fix for NullPointerException in Pnf - Fix: Since lambda expressions are evaluated lazily, Camunda flow results in an NPE being thrown if RuntimeService is not acquired as part of invoking thread. - Modified integration test CreateAndActivatePnfResourceTest to verify the fix.
