Sonar fixes to drools-pdp
Fixed most of the instances of the following sonar issues: Moved array designator Used diamond operator Changed System.out/err to use a logger Changed several Thread.sleep() in test code to a single sleep() Useless assignments Replaced comparison with "" to string.isEmpty() Merged if's Replaced ArrayList with List in method returns Reordered type modifiers Reordered constructor methods Defined constants for literals, or replaced them with method calls Removed "throws Xxx" for subclasses of RuntimeException Combined identical "catch" blocks Re-interrupted the current thread after catching an InterruptedException Removed tests against the literal "false" Fix indentation of new makeTopicOperError() method. Fix exception variable name in new methods, logNoUebEncoder() and logNoDmaapEncoder(). Change-Id: Iddae5210553662f733b67333b372dec8c3fe2c94 Issue-ID: POLICY-336 Signed-off-by: Jim Hahn <jrh3@att.com>
