Answer 1

For JDK6 you can download the source from java.net. For java.lang the story begins at j2se/src/share/native/java/lang/, and then search... JDK7 rearranges the directory structure a little.

Some methods, such as Object.hashCode, may be implemented by hotspot instead or in addition to through JNI/Java.

JDK6 is freely licensed through the Java Research License (JRL) and Java Internal Use License (JIUL). JDK7 and OpenJDK6 is licensed under GPL 2 with CLASSPATH exception (roughly speaking you can link to it without catching the GNU virus). I am not a lawyer.

(BTW: The real lawyers would like to point out that I am still an employee of Sun Microsystems. Sun UK is no more. It is now Oracle.)
