> With the move to non-blocking invocation, interceptors now use a lot of lambdas, sometimes in the form {{this::method}}. But the JVM doesn't cache this kind of lambdas, it only caches {{Class::method}} lambdas, so we end up creating lots of extra lambda instances.
> Of course, these are short-lived and are quite cheap to collect, but they can still pollute the processor cache.
