Actually, Hazelcast password was never really meant to provide any security. Please check this and this for details.
Hazelcast Security is an enterprise feature and, unfortunately, it can not be accessed in community version.

I need to download a particular version of the Java JDK, so I'm going to Oracle's website to do so. When I click any of the links to begin downloading a JDK, I get the following error message from my browser:
This is probably not the site you are looking for!
You attempted to reach download.oracle.com, but instead you actually reached a server identifying itself as a248.e.akamai.net. This may be caused by a misconfiguration on the server or by something more serious. An attacker on your network could be trying to get you to visit a fake (and potentially harmful) version of download.oracle.com.
You should not proceed, especially if you have never seen this warning before for this site.
Is this normal (i.e., does Oracle use akamai.net to host its JDK distributions), or does this suggest that Oracle or I are being attacked?
Neither Sun nor Oracle has ever used third parties to host JDK downloads in my experience since 1997.

A Java Servlet I maintain uses SSL encryption. I THINK it uses JSSE SSL by Oracle and after the HeartBleed Bug announcement I don't want to be using OpenSSL. Can someone tell me how I can be sure this is the case please?
So far I have found nothing on Google.
This isn't so much about the openssl command (which might not be on your path anyway) than about the OpenSSL library.
If you're using Tomcat, you would be relying on the OpenSSL library if you've set up the APR connector. Otherwise, you'll be using the JSSE (unless you've providing your own SSLImplementation classes, which is very unlikely).
I am not sure if I understand correctly but if you're trying to find out if your servlet is prone to heartbleed attacks and if it is reachable from the internet you might want to take a look at: http://filippo.io/Heartbleed/

Is it possible to (safely) start a java program from /etc/rc.local? I'm using Ubuntu Nov. 2011 (Why should I learn what #s the months are?).
If it helps (and can improve specificity), I'm running Minecraft 1.2.5 Bukkit Server, and yes, I have a script preprepared that sets up every thing to start the server (RAM, nogui, set working dir, etc).
Yes you can, try to look at this answer for a generic Java process:
Best way to daemonize Java application on Linux
Then specifically for Minecraft you can read this tutorial, and in particular this chapter.
Yes, you can.
Another approach is to create your own upstart script in /etc/init.d/. Take a look at /etc/init.d/skeleton and if it does make sense, make a copy of it and modify to suit your needs.
