I'd suggest the one that pops up on google, which is the <a href="http://jd.benow.ca/" rel="noreferrer">JD</a> Java decompiler.
It works really nice. 

As for the restrictions, you'd have to read a license of particular software, there might be written that any way of decompilation is forbidden.

I like <a href="http://jadclipse.sourceforge.net/wiki/index.php/Main_Page" rel="nofollow">JadClipse</a> - but it shows its age in places. You will need:

<ul>
<li>a jad binary</li>
<li>jadClipse installed</li>
<li>point the Eclipse preferences to the above jad binary</li>
<li>tell it to produce line numbers and align for debugging</li>
</ul>

There are several shortcomings:

<ul>
<li>code is produced sequentially, if byte code was rearranged so something comes late in the byte code but was early in the original source jad does not rewind to put the disassembled code to the right line. </li>
<li>jad does not understand Java 5 + 6 bytecode very well.</li>
</ul>

I have tried several decompilers and most of them have failed to produce a correct source for the applet I was trying to decompile (which was <a href="http://mrl.nyu.edu/~perlin/experiments/emotive-actors/" rel="nofollow">http://mrl.nyu.edu/~perlin/experiments/emotive-actors/</a>, in case anyone wants to reproduce).

The one which has worked absolutely flawlessly was <a href="http://www.sureshotsoftware.com/cavaj/index.html" rel="nofollow">Cavaj 1.11</a>, the code produced by it contains no syntax errors and the applet compiled from the sources runs identically to the original. What I was missing on the UI side was: Ctrl-A/Ctrl-C keyboard shortcuts not working, and no batch conversion available.

The other decompilers I have tried were:

<ul>
<li><a href="http://jd.benow.ca/" rel="nofollow">JD Java decompiler</a> (freeware) looks nice, but it made a lot of mistakes with variable declarations (some declarations were missing, other were placed badly)</li>
<li><a href="http://www.neshkov.com/" rel="nofollow">Neshkov DJ Java Decompiler</a> (shareware) also looks nice, the code produced by it contained less syntax errors then JD, but the code was not working. Given the product is not free, one would expect a bit more from it.</li>
</ul>

I can not answer your first question: it would be biased, perhaps...

About your second question, the decompilation is LEGAL. This point is very important for me. Take a look on this interesting page : <a href="http://www.program-transformation.org/Transform/LegalityOfDecompilation" rel="nofollow">http://www.program-transformation.org/Transform/LegalityOfDecompilation</a>

blocks|key|1460323|text|我发现JD非常好。尽管如此，我还是遇到了一两个小bug，它们导致了运行时的意外行为。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1460324|例如，我举了一个例子，原来的case语句在最后一个节点上没有'break‘(因为这自然是不必要的)，但由于JD最终对节点进行了重新排序，这意味着'default’case被意外调用。我还遇到了一个字符集的问题，我需要在结束时调用一些额外的toString()才能按预期注销。除此之外，它是伟大的！|1460325|我使用了另一个反编译器DJ来帮助我找出JD反编译的代码出了什么问题。但还有其他DJ无法处理的事情，所以我猜这两个反编译器的混合对我来说是有效的:)|1460326|希望Dupuy先生能读到这篇文章！|1460327|entityMap|0|LINK|mutability|MUTABLE|url|http://java.decompiler.free.fr/|1|http://www.neshkov.com/^0|3|2|0|0|0|B|2|1|0|0^^$0|@$1|2|3|4|5|6|7|T|8|@]|9|@$A|U|B|V|1|W]]|C|$]]|$1|D|3|E|5|6|7|X|8|@]|9|@]|C|$]]|$1|F|3|G|5|6|7|Y|8|@]|9|@$A|Z|B|10|1|11]]|C|$]]|$1|H|3|I|5|6|7|12|8|@]|9|@]|C|$]]|$1|J|3|-4|5|6|7|13|8|@]|9|@]|C|$]]]|K|$L|$5|M|N|O|C|$P|Q]]|R|$5|M|N|O|C|$P|S]]]]

I found <a href="http://java.decompiler.free.fr" rel="nofollow">JD</a> to be very good. Though, there were one or two minor bugs I came across that resulted in unexpected behaviour at runtime.

For example, I had an example where the original case statement didn't have a 'break' on the last node (because naturally this is unnecessary), but because JD ended up re-ordering the nodes it meant the 'default' case was called unexpectedly. I also had an issue with character sets where I required some extra toString() calls on the end of things for it to log out as expected. Apart from that it was great!

I used another decompiler <a href="http://www.neshkov.com/" rel="nofollow">DJ</a> to help me work out what was wrong with the code decompiled by JD. But there were other things that DJ couldn't handle, so I guess a mixture of both decompilers worked for me :)

Hopefully Mr Dupuy will read this!

Can you recommend a Java decompiler for Eclipse? My other questions is what restrictions is there for using a decompiled code from an other Java program? Illegal or what? I dont know much about licenses. Thanks for reading.
