Hello @stevejagodzinski
for your first example with enum, it’s fixed since SonarQube 8.5, I recommend updating your SonarQube instance, if it doesn’t solve this false positive, let us know.
for your second example with Pattern, I just created a ticket to not raise anymore when the user-controlled input is validated with a regex, I will inform you when it’s released.
thank you for this feedback
Eric
