Java Security

Post by KrispyKritter » Tue Mar 08, 2011 3:09 am

I don't remember Java doing this before.

When I clicked on a 'Download Java' link:
http://www.java.com/inc/BrowserRedirect ... w.java.com

It said I had the most recent version, but that
"Old and unsupported versions of Java have also been detected on your system. Click here for instructions on how to remove them to ensure your system security."
It displayed a link to the uninstall info page, which listed five old installs:

"We have detected the following old versions of Java that are installed on your system:

* J2SE Runtime Environment 5.0 Update 6
* J2SE Runtime Environment 5.0 Update 9
* J2SE Runtime Environment 5.0 Update 10
* Java(TM) SE Runtime Environment 6 Update 5
* Java(TM) SE Runtime Environment 6 Update 7

These should be removed to ensure your system security."

Aye, java is one of the more "unclean" runtimes in that most versions are backwards compatible, but they don't remove the previous versions on install...

I found you can manually do it... or use this:
JavaRa

Download and install and get the latest definitions pack, then remove all unwanted java runtimes and entries.

Yep, manual uninstall is what their instructions are, and I removed the old versions with no problems.

I had assumed Java was an 'additive' or 'layered' or whatever they call it, -type install. I had assumed it was like Win .NET framework, where you need to leave the previous versions installed. Programs written for each version of .NET need those specific versions to operate.

I double-checked that assumption and it was confirmed on this site, which lists the versions and has download links:

My versions were all installed by Windows Update with no muss nor fuss, but their sizes do total over 500MB.

Not exactly...

I've been a .Net framework programmer for a while now, and it was kinda a muck up on the part of MS.
Version 1.1 requires version 1.0.
Version 2.0 is standalone.
Version 3.0 requires version 2.0.
Version 3.5 requires version 3.0 (which requires v2.0).
Version 4.0 is standalone.

However, because of the way programming is implemented in .Net, you can write half a program in 4.0 and half in 3.5, requiring versions 2, 3, 3.5 and 4 to be installed before the program will run...

Yeah... They muffed that one up.
