RFR: 8207017: Type annotations on anonymous classes in initializer blocks not written to class file

[Vicente Romero]

Javac is not writing type annotations applied to anonymous classes inside of instance or static initializers. Basically for code like:


import java.lang.annotation.*;

class X {

    @Retention(RetentionPolicy.RUNTIME)
    @Target(ElementType.TYPE_USE)
    public @interface TA {
        String value() default "empty";
    }

    {
        class Local {}
        new @TA("LocalInstanceInitializerAnnonymous") Local() {};
    }

    static {
        class Local {}
        new @TA("LocalStaticAnnonymous") Local() {};
    }
}

not type annotations are generated as attributes of methods <init> or <clinit>. This PR is fixing this issue. The annotations are currently generated if the anonymous class is declared inside an instance or static method. The issue is only with initializers,

TIA
