Subject [DISCUSS] Donate Winegrower as Karaf subproject, OSGi flavor with flat/single classloader runtime
Date Tue, 29 Oct 2019 09:06:21 GMT
Hi guys,

For some months now, Romain and I worked on a PoC named Winegrower.

Winegrower provides three modules:

1. a Java runtime with OSGi programming model with a flat/single 

2. Winegrower "Cepages" are extensions (similar to spring-boot starter) 
that allows you to easily add flavors to your applications running with 

3. Java agent to add winegrower at low level and get turnkey feature 
like monitoring, etc.

We think Winegrower would be a great addition to Karaf for two reasons:

1. It's a first implementation about a flat/single classloader approach 
for OSGi. I know OSGi Alliance (and especially Ray) is thinking about that.

2. It's a great start to provide better tooling around OSGi and Karaf. 
The idea is to have

Just to be clear, you can develop an application and test it with 
Winegrower. Then, you can run the application using a simple JVM with 
the Winegrower Ripener or deploy in Karaf, it's up to you, depending of 
the use case.

The current Winegrower codebase is there:


You can take a look on the README and the examples.

We also deployed a quick website: https://jbonofre.github.io/winegrower/

Thoughts ?

JB & Romain
