From 7c62480edb52c829102cddd030384176bf16780b Mon Sep 17 00:00:00 2001 From: "k.kedron" Date: Fri, 24 May 2019 11:06:02 +0200 Subject: Improve unit test for ConfigurationUtils and sonar fixes Add more test for ConfigurationUtils. Fix error in getCompatibleCollectionForAbstractDef method bad return value for TransferQueue.class. Sonar fixes: - use not deprecated method IOUtils.toString. - remove code duplication. - return empty collection instead of null.
