Than I wonder what other distributions do? They probably just pick up 
files they need like here:

http://www.linuxfromscratch.org/blfs/view/cvs/general/openjdk.html

But I don't really know what is need it.

Good to know!

It seems to. But I just installed it to build Java itself. Plus also 
tried to build Tomcat and run its test suite.

But not really sure whether following directory structure is good enough:

usr/jvm/openjdk-11
usr/jvm/openjdk-11/bin
usr/jvm/openjdk-11/demo
usr/jvm/openjdk-11/lib
usr/jvm/openjdk-11/include
usr/jvm/openjdk-11/jmods
usr/jvm/openjdk-11/conf
usr/jvm/openjdk-11/man

In Solaris for JDK 8 we have:

usr/jdk/instances/jdk1.8.0

I mean "jdk" is probably better than "jvm"? Maybe I should try to keep 
existing structure.

Thanks!
