Re: [PATCH] Added OpenJDK Zulu compact profile base images and example apps for each profile

2016-09-14 Thread Waldek Kozaczuk 
Nadav,

I thought about reusing java-example but this would not work without
changing java-example/module.py.

Currently java-example/module.py relies on api.run_java() which uses
io.osv.isolated.MultiJarLoader which obviously would not work as compact
profiles do not have code to support isolated mode. That is why I
refactored runjava to support nonisolated mode that can be used with any
compact profile.

default = api.run_java(classpath=['/java-example'], args=['Hello'])

The java-compactx_example/module.py sets command line by using java.so
directly.

default = api.run('/java.so -cp /java-example Hello')

Presumably another way to fix it would be to change java-example/module.py
to be like java-compactx_example/module.py and then the need for these
three extra example apps would disappear.

Re: [PATCH] Added OpenJDK Zulu compact profile base images and example apps for each profile

2016-09-14 Thread Nadav Har'El 
Thanks, I committed these patches.

I think that the three separate example apps were not strictly necessary,
as one can do something like

   scripts/build image=openjdk8-zulu-compact1,java-example

to build an image with this specific version of Java and the same Java
example.
