Question

Looking for java source code from sun

Answer 1

+2 A:

Sun doesn't publish this. You can look at the implementation in OpenJDK or Apache Harmony to get some ideas.

It's not available?

I thought all the java source was viewable? ...Guess not.

Everything except the sun.* classes is in the normal JDK download, if I remember correctly. For sun.*, you have to use OpenJDK as Michael Barker says. I don't know if OpenJDK uses the exact same code or not.

Michael Myers 2010-02-01 22:34:03

Any sun.* class files are their internal implementation of the JVM, and they do not open source that part of it. They do open source the rest of the java libraries - i.e. "core" java

AFAIK, while they weren't published under a full open source license, these classes as well as the C++ code of the JVM have been available on the sun developer network for a long time.

@Michael Borgwardt: Where can I find them if they are published? Is this what you are referring to? http://download.java.net/jdk6/6u17/promoted/b04/index.html

@sixtyfootersdude It's been a long time since I looked at it, but looks like that's it, yes.

Answer 2

+3 A:

From the Open JDK (via google code search)

Michael Barker 2010-02-01 22:32:35

+1: Thanks for the input. What I really need is the exact class from the JRE (see update in question). But that might help with basic understanding.

Answer 3

+1 A:

Here is a link from docjar

Alternatively, use a decompiler. I used to use Jad a while back not sure if it still works for recent JREs.

+1; Thanks for the input. However this is not identical to one in the JRE. I am trying to figure out why this exception is being thrown. The stack trace looks like this: "at sun.net.www.protocol.https.HttpsURLConnectionImpl.getOutputStream(HttpsURLConnectionImpl.java:230)". Unfortionatly the line numbers don't match up. Thanks for the help though!

sixtyfootersdude 2010-02-01 22:45:17

Will a decompiler decompile onto the correct number of lines? Ie: will the exception stack dump line numbers correspond to decompiled code. I don't think so but it is possible (if the decompiler is smart)

sixtyfootersdude 2010-02-02 16:05:50

Jad has an option to add the original line numbers to each line.` -lnc - annotate the output with line numbers (default: off)`
