[Anthill] Multiple JDK's

[Eric Minick]

Curtis,

I think you were shooting for the AnthillPro list, but don't worry about 
it. Anthill OS people, he's discussing the Pro feature where you can 
have different projects use different versions of java to compile and 
test against.

Anthill itself runs on whatever JRE Tomcat is running in. Generally 1.2 
or better will work fine.

As for how builds with different versions of Java work, AnthillPro 
launches Ant in a separate process. When it does that, it sets 
appropriate environment variables like ANT_HOME, JAVA_HOME, and 
CLASSPATH. I believe that the other environment variables of the Tomcat 
user are conserved, with these being overridden.

This is done in the thread belonging to the build daemon controlling 
this build. If the future, we'll probably spawn another thread to better 
handle the cases where the called process hangs.

Don't worry about this sort of obscure question. It gives me a good 
chance to look back over things and make sure I understand how 
everything works. Good fun.

Cheers,

Eric
