Why not to make available for download Java source code?
As we know that in 1995 Java 1.0a version source code was available
for download in Internet!!!!!
Now many people have it!!

By March 1995, there were still only seven or eight binary copies of
what they called "1.0a" outside of Sun. The team was getting ready to
post a "full public" alpha version ("1.0a2") of the Java source code
on the Internet.

"We released the source code over the Internet in the belief that the
developers would decide for themselves," said Lisa Friendly.
