Yes that was my question, but for a static method isn't the current class and the class to which the static method belongs to the same?

I thought the original question was to find a way to remove the static class name. That's not anything that needs computation at runtime. The compiler can emit it.

Hi,
>From your blog I see that in JDK7 the code
MethodHandles.lookup().lookupClass()
returns the current class. I read it is also possible to get the current class from the stack trace.
However from a performance point of view wouldn't having a keyword of some sort to get the current class be more efficient than having to go-through the stack trace to determine the current class, or does the JVM also have to do the same thing to determine the current class?
Thanks
