--- Comment #3 from Remy Maucherat <r...@apache.org> --- As I see it, when a property doesn't exist (without errors) in the property source (SystemPropertySource), it should return null and the substitution isn't made. The source throwing an exception should mean there is an error. IMO it's time to clarify the behavior (probably only in 8.5 and 9) and warn on possible errors. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
