The defaults for node limits are very conservative. Only small methods should be inlined. The only exception are constants - an arbitrary number of constants is always allowed. Limiting to 1 node (which can be also 1 invoke) means that field accessors can be inlined and forwarding methods can be inlined. But null checks and class initialization checks are already putting a method above the limit. On the other hand, the inlining depth is generous because we do do not need to limit it. Note that more experimentation is necessary to come up with the optimal configuration. Important: the implementation details of this class are publicly observable API. Since Method constants can be produced by inlining lookup methods with constant arguments, reducing inlining can break customer code. This means we can never reduce the amount of inlining in a future version without breaking compatibility. This also means that we must be conservative and only inline what is necessary for known use cases.
