RFR: 8305007: Within-lambda subclass of local class using method param causes compiler crash

[Vicente Romero]

javac is crashing while compiling code like:


public abstract class CompilerCrashLambdaPlusLocalClass {
    public abstract void consume(Runnable r);

    public void doThing(String parameter) {
        class LocalClass {
            @Override
            public String toString() {
                return parameter;
            }
        }
        consume(() -> {
            class LambdaLocalClass extends LocalClass {}
            new LocalClass();
        });
    }
}

the reason for the issue is that the mappings for captured variables created by LambdaToMethod are not copying the `adr`, local address, field of the original VarSymbol it is mapping. Later on during code generation an assertion was being triggered due to a variable with an `adr < 0` this patch fixes this issue.

Thanks,
Vicente
