   >We should add direct .java invocation to this epic too. I have it already implemented on the devtools repo. [1]. The only reason I did not PR it to here was the gson dependency. Since we are taking care of it with this one, I see no reason not to implement it.

   >@gorkem I See no issue on adding .java also 
   @rabbah do you recall why this was not done originally for Java actions and only .jar?
   Maybe the extra latency for compile step on /init too bad or takes longer than 1minute those would be the only two I see, put that?s a problem we have today with swift with single source file it?s convenient for dev/demo but for production is better to have a precompiled to the action
   Maybe it?s time again to bring discussion of init actions that will help with compiling and saving the compiled output to the action stamping with runtime image and maybe source on the action this way it only compiled when the source changes or the runtime image changes.

   >Hum ?
   What about simple one liner functions between sequences  ?
   Meaning like to transform output parameters into input parameters in sequences
   Maybe there is a OW provider/operator that included libraries and frameworks into a custom runtime
   IBM including Watson sdk, COS SDK, Cloudant sdk, http client library
   RedHat including spring cloud framework and adapters
   Regular user extending a Java runtime with own libraries
   Someone offering a UI web based editor useful for demo to edit a java file in web editor assuming that runtime has some useful libraries installed like Jax-rs related ones to handle web actions input.

   >It?s nice to have - quick start, demo all good.

   >This has been my thinking last couple of days in these lines
   I am not sure where are storing the jars today when we say wsk action create foo foo.jar --main foo - is it as a blob in couchdb ??
   As you mentioned that biggest stuff we need to resolve dependency resolution for Java - wondering we can deploy a Maven Repo Manager as part of the OW deployment, this could solve the above point as well,. Right now the biggest hurdle of Java Adoption is this as functions need to be quick
