 capability is set

                 Key: HARMONY-3574
                 URL: https://issues.apache.org/jira/browse/HARMONY-3574
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
         Environment: linux and windows 32/64
            Reporter: Rustem Rafikov


Monitor events handling code does not check if the "can_generate_monitor_events"  capability
is requested. 
It make leads to performance degradation when running with jvmti. 
Typical code is: 

if (ti_is_enabled()) {
     // do something
}

Need to add VM_Global_State::loader_env->TI->get_global_capability(DebugUtilsTI::TI_GC_ENABLE_MONITOR_EVENTS)
as well probaly in ti_is_enabled() function (if it is used only for monitor events).
