Can anyone tell me if I really need Java 2 Runtime Environment, SE v1.4.2_03 and J2SE Runtime Environment 5.0 Update 3? These things are ridiculous. Each one is over 100MB! What a waste.

There is one comment on this post

  1. J2SE(TM) Runtime Environment 5.0 Update 6 ( is out. =)

    I don’t think you need versions earlier than, if version is installed. Basically, it’s supposed to be backward and forward compatible. It’s about a 16MB download, but the fingerprint is huge indeed: ~75MB.

    Now, if the question is about needing JRE at all… I know people who have neither the flash player plug-in nor the JRE installed, but some sites and applications are impaired. YMMV.

Add to the discussion:

I'll never share your email address and it won't be published.

What Is This? is the personal weblog of me, David Vincent Gagne. I've been publishing here since 1999, which makes this one of the oldest continuously-updated websites on the Internet.

A few years ago I was trying to determine what cocktails I could make with the alcohol I had at home. I searched the App Store but couldn't find an app that would let me do that, so I built one.
