General Java on iOS

[faroZ06]

I saw something called "JavaVM" on Cydia that lets you run Java stuff on iOS. I tried hosting a Minecraft server on my iPhone, and it seemed to work before eventually crashing and giving me "class missing" errors that appeared to be related to the Java VM being outdated.

My question is: Which version of the Java Virtual Machine is JavaVM for iOS?

try run the command

java -version

idk if the command will work, but I wont have access to iOS device for many hours.

Edit:
Removed one of two dashes in the command

Wow I must have been tired when I asked that question. I've used java -version many times before on my Mac. I got

java version "1.5.0"
JamVM version 1.5.1

which is SE 5, right? That's odd because this worked on an iMac G5 running Java SE 5. The error I am getting is about setting performance parameters:
