Incomplete implementation of GetFieldID and GetStaticFieldID
------------------------------------------------------------
Key: RVM-831
URL:
http://jira.codehaus.org/browse/RVM-831 Project: RVM
Issue Type: Bug
Components: Runtime: JNI
Affects Versions: 3.1.0
Environment: IA32, and Ubuntu
Reporter: Byeong Lee
Assignee: Byeong Lee
Fix For: svn head
Attachments: JNIGetFieldID.patch, TestJNIGetFieldID.c, TestJNIGetFieldID.java
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)
J9VM - 20090215_029883_lHdSMr
JIT - r9_20090213_2028
GC - 20090213_AA)
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.
