Should I uninstall out-of-date versions of Sun Java?

I installed Secunia PSI software on my laptop. As you may know, this software, which is free, allows you to check your computer for out-of-date software as this can make a computer vulnerable to security threats.

Secunia PSI is telling me that I have several, out-of-date versions of Sun Java on my laptop and that I should uninstall the old versions.

The Java.com website advises me that I "can safely remove older versions of Java" . However, the same page also advises me I "can also keep older versions of Java installed, in case you have an applet/application that still depends upon a previous version."

Users of Secunia PSI and Ask About Money have discussed this issue but no definitive answer was arrived at.

It may not be possible to give a definitive answer to this question right now but if someone could say that it is advisable to uninstall the out-of-date versions or that it's advisable not to do so, I guess that's the best I could hope for.

I would remove the older versions. Most Java programs that work in JDK1.4 work in Java 5.0 and later. I wouldnt bother keeping the older versions. Also, its unlikely you actually use java anyway, unless you actually run java applications/applets on the PC.

I removed all old versions of java without any ill effects.

Hi,

Just to let you know that I uninstalled old versions of Java on my PC using the JavaRa software, which can be downloaded from:

The software was recommended by Tech Support Alert, a site I trust very much.
