/**
* A {@link ClassVisitor} that remaps types with a {@link Remapper}.
*
* This visitor has several limitations. A non-exhaustive list is the following:
*
*
* - it cannot remap type names in dynamically computed strings (remapping of type names in
* static values is supported).
*
- it cannot remap values derived from type names at compile time, such as
*
* - type name hashcodes used by some Java compilers to implement the string switch
* statement.
*
- some compound strings used by some Java compilers to implement lambda
* deserialization.
