Hi Amy, Tristan,

I'm not a Reviewer kind of reviewer, but I've started to look at the
code and can sponsor this.

Some comments on test/java/lang/reflect/Method/invoke/

As there are a lot of non-public top-level classes perhaps this test
should be in it own directory.

It is very hard to read the data table:

292             {interface1.class, 1, 1, new Object1(), new Object[]{},
293                 new Object[]{}, "interface1", null},

I believe you should move the methodsNum constant and the declMethods
num constant to an annotation on the interface/class in question. For

@MyTestData(numMethods=1, declMethods=1)
41 interface interface1 {
42     @DefaultMethod(isDefault = true)
43     @StaticMethod(isStatic = false)
44     @ReturnValue(value = "interface1.defaultMethod")
45     default String defaultMethod(){ return "interface1.defaultMethod"; };
46 }

That way it is much easier to inspect that the constants are right.

The same can probably be done with the return values encoded.

Instead of all these "new Objects[] {}" can't you create a field,

Object [] EMPTY_PARAMETERS = new Object() {}

and reuse it?

That way it will be much easier to verify that the encoded test data is

I'll comment on the other tests shortly.
