It took Java until Java SE 14 (last year) to produce NPE stacktraces which actually tell you which variable was null. At least in Rust third parties could have created a library to remedy a similar situation.

For whatever reason, it look a long time for parameters and locals to have a name in addition to a slot and a type in the JVM bytecode. Before that data was introduced, it was an impossible task. Also why things like de-/serialization frameworks required annotations on parameters duplicating the parameter name.
