From 04c607ef77edb757a43b24c8bff233fad6ede4de Mon Sep 17 00:00:00 2001 From: "Benjamin, Max (mb388a)" Date: Mon, 17 Sep 2018 09:47:02 -0400 Subject: Accept header not honored when building exception added accept headers to http entity request mappers were looking at "Content-Type" and not "Accept" modified test to no longer share global headers added additional tests and corrected comparison errors Fixing issue with comparing media types, the equals method in MediaType.class uses parameters as well to compare, added a method to just compare the type and subtype and get done with it Fixing test failures, getMEdiaType would come as null in most cases, this causes the defautl serialization mode to be picked which is xml. tests now pass with exception providers in place exception providers now handle JSON and XML Dumy push to re-trigger the build which failed at sonar evaluation Trying to fix the build by removing different spy's Returning XML instead of JSON in cases of error for endpoints. Removed exceptions and its generic handler which is a good thought, however given that the exceptionhandlers are generic it gets tough to return to handle exceptions which require different namesaces in response amongst other problems.
