I'm going to make an annotation that works at a field level similar to Lombok's #Getter.
However, no examples were found available in that higher class by manipulating AST at the field level.
Where can I find an implementation of this?
I referred some blog. (e.g. https://www.happykoo.net/#happykoo/posts/255)

Any idea?
How can I generate documentation using already present code in java class / classes. As the java class changes, I would want it to reflect in documentation automatically.

There are some tools available on the market that scan your code and generate a documentation for it. A known tool which does it, and my favourite, is Javadoc. It also allows you to add annotations to the code which later be reflected in the documentation.

I want to implement JUnit tests in order to do some refactoring. First I'd like to check how good the class is, whether it's implemented for testability. Is there any metric and tools I could use to measure how testable a Java class is?
Probably you're looking for the Testability Explorer. Latest code seems to be on github.

I just wanted to do some research and wanted to generate the VirtualMachineError.
Can any one tell me how can I generate VirtualMachineError?
A StackOverflowError is a VirtualMachineError, so you can provoke such an error by running a recursion without a basecase. (But why?)

How does one instantiate all classes in a program, that are in different packages and haven't already been instantiated?
You only instantiate instance of a Class.
You can initialise a Class by attempting to access it. e.g.
Class.forName("mypackage.MyClass");
You can scan your class path to find all the classes in a package and load them this way.
Note: while you can do this, it is highly unlikely to be a good idea. There is usually a better alternative.

I'm using the Java package com.sun.rowset.CachedRowSetImpl. Can you tell me is there a new Java package in Java 7 which I can use instead of this package?
You should be using the javax.sql.* package directly. Read the javadoc, and consider implementations of CachedRowSet here
