Resolution: Fixed
Patch applied at 538681. Please check that JVMTI now reports correct micro version.
> [drlvm][jvmti] compatibility: GetVersionNumber returns the value with zero micro version
> ----------------------------------------------------------------------------------------
>
> Key: HARMONY-3799
> URL: https://issues.apache.org/jira/browse/HARMONY-3799
> Project: Harmony
> Issue Type: Bug
> Components: DRLVM
> Reporter: Vera Petrashkova
> Assigned To: Gregory Shimansky
> Priority: Minor
> Attachments: GVN.zip, H3799.patch
>
>
> According to JVMTI specifications
> GetVersionNumber returns value which is the version identifier.
> The version identifier includes major, minor and micro version as well as the interface type.
> DRLVM returns version identifier which contains zero micro version while
> RI returns version number which parts equal:
> major = 1, minor = 0 and micro = 36
> It looks like DRLVM returns version number which equals to JVMTI_VERSION_1_0.
>
> To reproduce this run the following test:
> ---------------GVN.java-------------
> public class GVN {
> static public void main(String args[]) {
> return;
> }
> }
> ------------------------------GVN.cpp------------------------------
> #include <stdio.h>
> #include "jvmti.h"
> static jvmtiEnv *jvmti = NULL;
> JNIEXPORT jint
> JNICALL Agent_OnLoad(JavaVM *jvm, char *options, void *reserved) {
> jvmtiError err;
> jint res;
> jint ver_ptr;
> jint micro_rt;
> jint minor_rt;
> jint major_rt;
> res = jvm->GetEnv((void **) &jvmti, JVMTI_VERSION_1_0);
> if (res != JNI_OK || jvmti == NULL) {
> return JNI_ERR;
> }
> err = jvmti->GetVersionNumber(&ver_ptr);
> fprintf(stderr,"Version number: %x JVMTI_VERSION_1_0: %x \n", ver_ptr, JVMTI_VERSION_1_0);
> major_rt = (ver_ptr & JVMTI_VERSION_MASK_MAJOR) >> JVMTI_VERSION_SHIFT_MAJOR;
> minor_rt = (ver_ptr & JVMTI_VERSION_MASK_MINOR) >> JVMTI_VERSION_SHIFT_MINOR;
> micro_rt = (ver_ptr & JVMTI_VERSION_MASK_MICRO) >> JVMTI_VERSION_SHIFT_MICRO;
> if (micro_rt > 0 ) {
> fprintf(stderr, "PASSED\n");
> } else {
> fprintf(stderr, "FAILED\n ");
> }
> fprintf(stderr, "\tRuntime version: %d.%d.%d\n", major_rt, minor_rt, micro_rt);
> fflush(stderr);
>
>
> return JNI_OK;
> }
