Changes on ".NET Application" pattern in Quebec causing Service Map's discovery to update different applications into .NET applicationDescriptionIn Quebec, we introduced new fallback logic to get the version in .NET Application pattern.This is the fallback step:=====9. If version is empty - find .NET version=====This step's validation is not strong enough as it might catch exception on the response. Example: "Cannot open file xxx"This response is then set as the version and the logic thinks it is a .NET application. As a result, your previous application would be replaced with .NET application flow. This is incorrect.Steps to Reproduce Build a service map with discovery that contain application like Tomcat in Paris instance.Upgrade instance to Quebec.Change step 9 of .NET application pattern so that it will return the version's value with invalid string. Example: "Cannot open file".Observe that your previous Tomcat application is now replaced with .NET application.WorkaroundThis problem is currently under review.
