How single line Java comment is accepted without starting by //?

Question

When I put some comments on my Java code
I miss to put // in the start of the comment line (its content: url)
I expect compilation error but i surprised the comment line is accepted!
Note: I use Java7

// below single line java comment is accepted without starting by //
https://www.google.com/

Kindly any explanation?

`https:` is a valid label (see e.g. https://docs.oracle.com/javase/tutorial/java/nutsandbolts/branch.html), the rest is a comment. — jonrsharpe, Jun 04 '18 at 13:23
