David Grove commented on RVM-831:
---------------------------------

Hi BK,

Are you actually working with a more complex example in which the order of traversing superclasses vs. superinterfaces matters?  The current svn head passes the extended test case for me.  So unless it is a question of ordering (the field is declared in both an interface of this class and as a field of a superclass and we are supposed to find the interface one in preference to the superclass one), then I don't see why it isn't working for you.

> Both GetFieldID and GetStaticFieldID does not correctly run the test case which I attach. 
> Jikes RVM produced  wrong results, which are different from what Hotspot 1.6.0_13 and J9 1.6(SR4) showed:
> $rvm TestJNIGetFieldID
> instance_a: fail
> static_s: fail
> static_f: fail
> $java -showversion TestJNIGetFieldID
> java version "1.6.0_13"
> Java(TM) SE Runtime Environment (build 1.6.0_13-b03)
> Java HotSpot(TM) Server VM (build 11.3-b02, mixed mode)
> instance_a: pass
> static_s: pass
> static_f: pass
> $java -showversion TestJNIGetFieldID
> java version "1.6.0"
> Java(TM) SE Runtime Environment (build pxi3260sr4-20090219_01(SR4))
> IBM J9 VM (build 2.4, J2RE 1.6.0 IBM J9 2.4 Linux x86-32 jvmxi3260-20090215_29883 (JIT enabled, AOT enabled)

> JCL  - 20090218_01
> instance_a: pass
> static_s: pass
> static_f: pass
> GetFieldID could not handle a hidden instance field, and GetStaticFieldID could not find 
> a static field in super classes or interfaces. I attach my patch.
