Hi,
I know AnnotatedElement is not a common class to implement outside of the
JDK. But the interface introduces some new methods that will break
existing
code.
I must admit I am surprised as I thought that any new methods on
interfaces would have to have default implementations to avoid this kind of
breakage. Seems to me that defaults should be possible for those new
methods. Perhaps this is still a work in progress?
OpenJDK could invest more in static analysis tools. Here it would be good
to use a tool to audit all interfaces to check that new methods without
defaults have not been added.
Hi Martin,
FWIW, with my ccc hat on, I've previously (internally) asked the JCK
team to run such reports. IIRC, the methods on AnnotatedElement where
the only potentially problematic ones made so far. (We'll be added
methods to interfaces over in javax.lang.model.*, but we can't use
default methods over than and we explicitly warn implementers and user
of the API of the potential for new methods.)
Thanks,
-Joe
