Is void a Java primitive type??
In the API java.lang.Void describes "The Void class is an uninstantiable placeholder class to hold a reference to the Class object representing the primitive Java type void." but in the JLS void is not included.
For the exam, should i stick to the JLS?

You are looking at two different uses of the word. Lower case v void is the method modifier that signifies no return value, it is not a primitive. Upper case V Void is - as you found - a placeholder used in reflection. I dunno why the JavaDocs say:

the primitive Java type void.

since void is not a primitive type.

We discussed that issue some times ago in the following thread: http://www.javaranch.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic&f=24&t=013732
As far as I am concerned I think the reason why the API tells that is because of a silly cut-and-paste made by the guy who wrote the class java.lang.Void.
