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 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)

I am trying to learn Kotlin and I read that it is compatible with Java.
Can I define all of my classes in Kotlin and instantiate them in a Java controller class?
Yes, if you have both Kotlin and Java files in your project, you can refer and create new objects of Kotlin class in Java.
This shows how you can setup such a project in Maven:

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 am trying to check if methods that acquire a resource also release it. What is the best tool to use to find out callers of a method in the classes in a single jar file? Can I do this with CheckStyle or FindBugs? How?
I guess I can do this using BCEL or such-like, but I have never worked with byte-code before and would take too long to do this.
Searching for "java call graph" did not find anything useful, but this seems to be a very basic functionality so I probably missed a good match. However, I would like to not have to generate the entire call graph on this very large project.
