I am using an open source java framework that includes several jar packages. I would like to get to know the architecture of the framework so I am looking for a free tool that does reverse engineering.
Particularly I m looking for a tool to generate Uml diagrams (or just the class hierarchy and maybe the dependencies among packages) from the Java source code.
Anybody knows such a free tool?
The tool I used was ObjectAid and I found it as a good tool.
if you are workiing with netbeans: http://www.visual-paradigm.com/support/documents/vpumluserguide/2381/2384/66565_reverseengin.html

eclipse : eclipse UML
Modelio with this Java module are able to do so...

I'm not asking for an opinion here - just a fact: is there a plugin, tool, or technique that lets me write classes or at least method bodies directly in bytecode in Java in either Eclipse or IntelliJ, and what is it? I'm not looking for runtime codegen, I want this at compile time.
I found one here: https://plugins.jetbrains.com/plugin/8461-bytecode-editor but there is no download link and I have no idea how to build it (I tried, I really did). But it's basically everything I want.
In .NET I use the excellent IL Support plugin for this, but I haven't found a similar solution for Java.
There is a download link on that page but you don't need to download it directly so that doesn't matter. IntelliJ provides a plugin installer In Settings>Plugins. At the botttom of the Plugins page is a button to 'Browse repositories'

I am currently working on a Java project with "IBM Rational Software Architect"(Licensed Version) as an IDE .My task is to understand the code flow and need to prepare Technical Document as the project is very big (a lot of codes, classes, packages, etc) and undocumented. Since, the project is written in Java, my idea was to reverse engineer this project to see its architecture in UML. Do suggest me any open source software/ plugin that suits my IDE and can complete the task very easily?
I googled and found many useful Tools for Eclipse IDE but not for IBM Rational Software Architect.
Thanks for your answer !!
StarUML is a good open source tool, I think it have what you desire.
You should consider stand-alone products. For generating sequence diagrams and jar dependencies dynamically try jSonde
Static code analysis will suit for class diagrams - any modern IDE (like IntelliJ IDEA) can generate it
You can try "Modelio" which is Open Source and can reverse and generate class diagram.

I have created java entity classes inside a given package. I want to create a UML diagram for those java classes in the package. Any one know how to do it in NetBeans IDE 7? (I installed the plugin and it is working.)
For those using Netbeans version 8, take a look at these plugins
easyUml -> http://plugins.netbeans.org/plugin/55435/easyuml
PlantUml ->http://plugins.netbeans.org/plugin/49069/plantuml
Visual Paradigm is a software which also helps in generating UML diagrams.

The normal Organize Imports behavior of Eclipse can make some silly suggestions. For instance, despite using java.util.Collections in a good number of my classes, occasionally the edu.emory.mathcs.backport Collections class will be imported instead.
I have blocked some of these silly packages in the Java -> Appearance -> Type Filters section of the preferences, but if there were a plugin that can figure this out automatically it would be quite helpful.
There is a Plugin (Code Recommenders Developer Tools) which should priorize the classes you prefer based on statistics. So the entries in the dialog are ordered based on their using.
It is included in eclipse kepler, but also available for older versions.

I am looking for a translator for translate Java ByteCode to Machine Native Code before execution to improve performance.
I heard that OpenOffice is made with JAVA, but I can't see any jar file in his installation folder, therefore, maybe there is a translator but I can't find it.
Does anyone know some tool or comercial product to do that?
Thanks!
There are multiple solutions. All are not ideal.
Take a look here (exe4j). To learn more read this article.
Give a look to Avian JVM. See my reply here to this question for pointers on how to embed it and what class libraries you can use to generate your stand-alone executable.
if you just need a managed language/platform, you can also use .NET/Mono AOT. See the mkbundle tool included with Mono 2.x.
Please have a look into https://www.graalvm.org/.
It could build a native image from your jar and run it as binary (native code).
