Online user guide for jconsole is wrong

[kiriyama.takuya at fujitsu.com]

Hello.

The URL to the online user guide on the help menu in JConsole is wrong in Java 15.

Now this URL is:
http://docs.oracle.com/javase/15/docs/technotes/guides/management/jconsole.html
However, the the online user guide page pointed by this URL doesn't exists.
It should be:
https://docs.oracle.com/en/java/javase/{java version}/docs/specs/man/jconsole.html
The page pointed by this URL exists for Java 12, 13, 14 and 15.

Please consider the following code:
