TODO: should delay some checks to
canInline
(during inlining) problem is: here we don't have access to the callee / accessed field, so we can't check accessibility- INVOKESPECIAL is not the only way to call private methods, INVOKESTATIC is also possible
- the body of the callee can change between here (we're in inliner heuristics) and the point when we actually inline it (code may have been inlined into the callee)
- methods accessing a public field could be inlined. on the other hand, methods accessing a private static field should not be inlined.

- Deprecated
(Since version 2.12.16) Use
formatString.format(value)
instead ofvalue.formatted(formatString)
, or use thef""
string interpolator. In Java 15 and later,formatted
resolves to the new method in String which has reversed parameters.
