Daniil,
I forgot to ask you an output log of new tests.
Could you, please, inline it in your reply?
Thanks,
Serguei

Hi Daniil,
The fix looks pretty good to me.
Just minor comments.
http://cr.openjdk.java.net/~dtitov/8216324/webrev.01/src/hotspot/share/prims/jvmtiEnv.cpp.frames.html
2519 int skipped = 0; // skip default methods from superinterface (see JDK-8216324)
You can say just: // skip overpass methods
There is probably no need to list the bug number.
2523 // Depending on can_maintain_original_method_order capability 2524 // use the original method ordering indices stored in the class, so we can emit 2525 // jmethodIDs in the order they appeared in the class file 2526 // or just copy in any orderCould you, please re-balance the comment a little bit?
Also, the comment has to be terminated with a dot.
Replace: "or just copy in any order" => "or just copy in current order".

114 default void default_method() { } // should never be seen
The comment above is not clear. Should never be seen in what context?
117 interface OuterInterface1 extends DefaultInterface {
An extra space before "extends".

I like the test simplicity.
Default methods are always in interfaces.
I'd suggest to rename the test to something like: DefaultMethods.java or OverpassMethods.java.
http://cr.openjdk.java.net/~dtitov/8216324/webrev.01/test/hotspot/jtreg/serviceability/jvmti/GetClassMethods/libInterfaceDefMethods.cpp.html
44 if (options != NULL && strcmp(options, "maintain_original_method_order") == 0) { 45 printf("maintain_original_method_order: true\n"); ... 54 } else { 55 printf("maintain_original_method_order: false\n");I'd suggest to remove the lines 54 and 55 and adjust the line 45:
printf("Enabled capability: maintain_original_method_order: true\n");
88 jobject m = env->ToReflectedMethod(klass, methods[i], (modifiers & 8) == 8);It is better to replace 8 with a symbolic constant.
Thanks,
Serguei

Thanks for handling this.

Please review change [1] that fixes GetClassMethods behavior in cases if a default method is present in a super interface. Currently for such cases the information GetClassMethods returns for the sub-interface or implementing class incorrectly includes inherited not default methods.
The fix ( thanks to Alex for providing this patch) ensures that overpass methods are filtered out in the returns. The fix also applies a change in the existing test as David suggested in the comments to the issue [2].
Testing: Mach5 tier1-tier3 tests successfully passed.
