[runtime/metrics](/pkg/runtime/metrics/) counter
named `/godebug/non-default-behavior/<name>:events`
that counts the number of times a particular program's
behavior has changed based on a non-default value
for that setting.
For example, when `GODEBUG=http2client=0` is set,
`/godebug/non-default-behavior/http2client:events`
counts the number of HTTP transports that the program
has configured without HTTP/2 support.

## Expected Behavior
<!--- If you're describing a bug, tell us what should happen -->
<!--- If you're suggesting a change/improvement, tell us how it should work -->

## Current Behavior
<!--- If describing a bug, tell us what happens instead of the expected behavior -->
<!--- If suggesting a change/improvement, explain the difference from current behavior -->

## Possible Solution

        private final CtBehavior behavior
        private final String behaviorName

        NullableMethodVisitor(CtBehavior behavior) {

            this.behavior = behavior
            this.behaviorName = behavior instanceof CtConstructor ? "<init>" : behavior.getName()
        }

But if for some reason your clients depend on the old behavior, you can revert to it by overriding the method `make_not_authenticated_error` in your security classes.
