Headless JDK7 for embedding

Question

Where can I find the headless version of JDK7 for the linux-i586 architectures?

I couldn't find anything on Oracle's page, maybe I am just blind, or there is no such pre-compiled JDK...

The purpose is that I want to port the runtime library of the JDK to a operating system with a custom JVM, and I think this should be the one suiting best for my needs.

AFAIK there isn't a special headless version of Java 7. But you can easily tell ordinary Java to run in headless mode. For example:

java -Djava.awt.headless=true com.acme.project.Main

For more information on headless Java, read this Oracle page:

• Using Headless Mode in the Java SE Platform

I would need this version to keep it as slim as possible.

Your only options would appear to be:

• Ask Oracle if they can provide you with a special build (for money!!!).

• Attempt to create your own stripped down build from the OpenJDK sources.

Beware that the Oracle binary distribution licence forbids you from distributing a JRE produced by "cutting down" a normal one. I don't know if this applies to a JRE that you have built from source code. Read the relevant license agreements carefully.

But my advice would be to just use a standard JRE installer.
