Jigsaw and containers

[Remi Forax]

Hi Daniel,
several points first,
the JRE doesn't exist anymore apart for compatibility (the jre is just a bunch of modules) and a jar can be a modular jar, just have a module-info.class in the jar, so applications that uses jars can be modular, they do not have to use jlink.

So you can have a jlink image as small as just java.base and all your applications and their dependencies as modular jars, the modules will be shared by the different applications, or a jlink all applications and have no sharing at all and all the states in between.
