https://bugs.openjdk.java.net/browse/JDK-8216324

Hi,
We recently discovered something similar, although with the native
counterparts of getDeclaredMethods: the JVM-TI function
GetClassMethods and the JDI method ReferenceType.methods().
The documentation for which states "Only directly declared methods
are returned (not inherited methods)" or "(...) declared directly in
this type. Inherited methods are not included."
When running the code pasted below with HotSpot (tried OpenJDK8 and
11), I get the following output:
[public abstract java.lang.String app1.Test$Child.method2()]
[public default java.lang.String app1.Test$Child.method(), public
abstract java.lang.String app1.Test$Child.method2()]
This would appear to be a bug with JVM TI in how default methods are
accounted for. GetClassMethods simply looks at the methods defined in
the instanceKlass, but for interfaces default methods are included. I'll
look into this in more detail and file a hotspot bug.
An interesting thing is that it's not the default method "def" that is
listed, but the abstract method "method" (with incorrect modifier?)
Sorry yes I misread the original code and just looked at the extra
"default method" in the output. Definitely something not right there.
Thanks,
David
