From 4401819b97be13c244dfe206256b59d13c89f7a6 Mon Sep 17 00:00:00 2001 From: Jim Hahn Date: Wed, 31 Jan 2018 17:49:08 -0500 Subject: Fix sonar issues in feature-state-management DroolsPDPIntegrityMonitor.java: Modified init() to throw just IntegrityMonitorException. Modified DroolsPDPIntegrityMonitor init() method to throw specific types of exceptions. StateManagementFeature.java: Sonar complained about needing to merge "if" statements, but chose to eliminate the "if(logger.isDebugEnabled())" instead - did this through-out the source file. Removed extra runtime exception from "throws" declaration. DbAudit.java: Fixed sonar issue regarding setting a static variable from within a non-static method. Removed logger.isDebugEnabled() tests where method calls are not involed. Simplified invoke() method complexity as reported by sonar. DroolsPDPIntegrityMonitor.java: Reduced init() complexity reported by sonar.
