Enable JVMPI_EVENT_OBJECT_ALLOC, and disable it, and enable it again. Then this
event is not sent. But classc VM is OK. This poroblem is only HotSpot VM problem.

I implement the fix for bugid:4449231, but couldn't get the improvement.

------------------------------------------------------------------
#include "jvmpi.h"

JVMPI_Interface *jvmpi_interface;
#define CALL(f) (jvmpi_interface->f)

static void notify_event(JVMPI_Event *event)
{
switch(event->event_type) {
case JVMPI_EVENT_OBJECT_ALLOC:
print("object_alloc\n");
break;
default:
break;
}
}

JNIEXPORT jint JNICALL JVM_OnLoad(JavaVM *jvm, char *options, void *erserved)
{
if((*jvm)->GetEnv(jvm, (void **)&jvmpi_interface, JVMPI_VERSION_1) < 0)
return JNI_ERR;

jvmpi_interface->NotifyEvent = notify_event;

CALL(EnableEvent)(JVMPI_EVENT_OBJECT_ALLOC, NULL);
CALL(DisableEvent)(JVMPI_EVENT_OBJECT_ALLOC, NULL);
CALL(EnableEvent)(JVMPI_EVENT_OBJECT_ALLOC, NULL);

return JNI_OK;
}
