This code that we have elsewhere in the debug agent seems to compile ok. 
Perhaps all that is needed is a cast of JVMTI_VERSION to jint:


static jboolean isVersionGte12x() {
    jint version;
    jvmtiError err =
        JVMTI_FUNC_PTR(gdata->jvmti,GetVersionNumber)(gdata->jvmti, &version);

    if (err == JVMTI_ERROR_NONE) {
        jint major, minor;

        major = (version & JVMTI_VERSION_MASK_MAJOR)
                    >> JVMTI_VERSION_SHIFT_MAJOR;
        minor = (version & JVMTI_VERSION_MASK_MINOR)
                    >> JVMTI_VERSION_SHIFT_MINOR;
        return (major > 1 || (major == 1 && minor >= 2)) ? JNI_TRUE : JNI_FALSE;
    } else {
        return JNI_FALSE;
    }
}
