From 3495931d999bd8022724c6fea0166baf01b5e113 Mon Sep 17 00:00:00 2001 From: Jim Hahn Date: Thu, 2 Sep 2021 12:18:49 -0400 Subject: Create methods for creating temp files Created utility methods to create temp files and set default permissions. These can be used in other repos to satisfy sonar. Also added code to close streams and clean up temp files created by some junit tests. Modified to use IOUtils to read a stream.
