No, I just tried it myself and got the message too. I'm not sure if you would need to update Java or not, I don't think you do. Java 6 should work fine.
You really only need to have at least the minimum Java version we tell you to have on the download page. The reason is because we call various methods that are introduced in like Java 7. LGM is still supposed to start and run fine but if you click a button that uses some like Java 7 feature it will throw an exception. If you never run into the part of the program that uses that feature, you'll have no problem using it on really old Java versions. It's actually very clear what the error is when that happens too, because LGM shows its own message when you start telling you to update Java. So updating Java is not likely to fix this or other issues unless there happens to be a bug in the JVM causing your issue, which is sometimes the case.

Answer these questions please:
* Was this a fresh download of the portable ZIP?
* Were you trying to update an old portable with the new LGM and plugin? That may not work because there are changes on GitHub to the extension descriptors that means you need to pull from master.
* Did you try pulling from master but not updating LGM or the plugin?
If this was not a fresh download of the portable ZIP, please try download the fresh one from GitHub releases page.https://github.com/enigma-dev/enigma-dev/releases
