Add support for Java 11 to deprecated Timings API

In Java 11 the internal reflection method used to determine the calling
class in the legacy and deprecated Timings API, that no one should be
using anymore, was removed.

This means plugins that try and use it will all fail to enable and we
can't compile the server with JDK 11.

The solution to the removal of this internal reflection class is
to just use reflection to call it if its available and fall back to
the unnamed handler system if it isnt.

Update to the newer API if you use Timings already...
