Want to debug the source code of JDK

Question

I have the problem same as this.

I just tried to figure out how does hashmap internally works. So I want to debug the source code of SDK.

Currently. I think What I am looking for the compiled version with debug information for Java SE 1.7. i.e. compile using javac -g.

I think I am not the only guy who want to do this. So anyone who knew the link or already done this before. (Sorry for I am the lazy man.Forgive me that. ) Please kindly share the work result for me. Well appreciated. Thanks.

*compiled version with debug information* -> Do you mean *byte-code*? — TheLostMind, Mar 01 '16 at 09:34
I meant the compile result of `javac -g`. as the link I mentioned in my question suggested. Thanks. — Joe.wang, Mar 01 '16 at 09:38
There is a src.zip file in jdk folder which has the source code for java files. Isn't that what you're looking for? — Pallav Jha, Mar 01 '16 at 09:41
Yes, I had made it. Just followed the `jre\lib\endorsed solution`, It works well. Thanks! +1 — Joe.wang, Mar 01 '16 at 11:54

You do need to compile those classes with debugging yourself.

Distributing such a package would probably be a violation of Oracles License Agreement.

The post you linked has detailed instructions on how to do that.

The link in my question actually answered my question. But I just want to add missed part it didn't mention. The endorsed jar file should be joined in the installed JRE as an external jar otherwise it doesn't work. Thanks.
