[JavaSymbols] Annotation on backing field of synthesized property from Java is dropped

[juliamcclellan]

What is happening? What should have happened instead?

Relates to #4513

Without the experimental java symbol analysis flag enabled, the DProperty synthesized from a Java private field with public accessor methods has annotations from the Java field. With the symbol analysis enabled, the annotation on the field no longer appears on the DProperty.

This scenario seems like it should be equivalent to a regular Kotlin property with a @field annotation, which does have the annotation appear on the DProperty.

If the Java field is public, then the field annotation appears on the DProperty when the symbol analysis is enabled.

Reproducer

package test.pkg
annotation class Anno

package test.pkg;
public class JavaClass {
    @Anno
    private int foo = 0;
    public int getFoo() { return foo; }
    public void setFoo(int foo) { this.foo = foo; }
}

package test.pkg
class KotlinClass {
    @field:Anno
    var foo: Int = 0
}
