Is Java necessary to create an AMI?

I've been reading Amazon EC2 doc, and you can create the AMI with the AMI tools, but, for registering (and then be able to use it for insert in new instances), you need EC2 API tools, and they need Java.

Is it necessary then to install all Java package in a host, to regi开发者_JAVA百科ster a just created AMI?

I find it unnecessary because Java installation takes too much space and performance.

Use the Amazon GUI to create the AMI instead?

Not all the tools require java, you can use the ruby ones for example

However these are not offical tools, but 3rd party created tools.
