I tried to remove `this->` from my change, but errors occurred as below;

```
In file included from
/home/ysuenaga/OpenJDK/jdk/src/hotspot/share/gc/shared/collectedHeap.hpp:36,
                 from
/home/ysuenaga/OpenJDK/jdk/src/hotspot/share/precompiled/precompiled.hpp:37:
/home/ysuenaga/OpenJDK/jdk/src/hotspot/share/utilities/events.hpp: In
member function 'void TemplatedStringEventLog<bufsz>::logv(Thread*,
const char*, __va_list_tag*)':
/home/ysuenaga/OpenJDK/jdk/src/hotspot/share/utilities/events.hpp:156:10:
error: there are no arguments to 'should_log' that depend on a
template parameter, so a declaration of 'should_log' must be available
[-fpermissive]
     if (!should_log()) return;
          ^~~~~~~~~~
```

So I want to keep `this->`.


Thanks,

Yasumasa
