A DESCRIPTION OF THE PROBLEM :
When I press tab after "Math" or "Math.abs(", I get tab completion & am able to access information such as method signatures & Javadoc.
Annotations should have similar tab completion. So pressing tab after "@Deprecated" should behave the same as doing so after "Deprecated". And pressing tab once after "@Deprecated(" should show a list of the annotation's elements. Additional tab presses should show the Javadoc of each element in turn, just like doing so for a method shows the Javadoc of each method overload in turn.
