-----------------------------------------------------------------
I have been making changes to pass the caller-bundlecontext to the scala
compiler service. But just letting the SSP's bundle load the compiled SSP does
not work because it doesn't know about SRenderlet and CompiledScalaServerPage
classes.
Next I wrote some (not very nice) code to get a bundle's class loader (it's not
that easy, I used java reflection) and tried to make a custom ClassLoader. The
idea is to use the Bundle's class loader as parent class loader with the custom
class loqader. The custom classloader was at first the currently used
AbstractFileClassLoader which enabled the CompiledScalaServerPage class to be
resolved. However it still does not resolve the SRenderlet class. I started
extending the custom class loader to load all classes in the scala scripting
bundle's classpath but so far I failed at making it work in Scala. I am still
working on it.
All this code is very prototypical and probably is not very efficient. The idea
was more the see if it can be done.

> Key: CLEREZZA-617
> URL: https://issues.apache.org/jira/browse/CLEREZZA-617
> Project: Clerezza
> Issue Type: Bug
> Environment: Mac OSx 10.6.6
> java version "1.6.0_26"
> Java(TM) SE Runtime Environment (build 1.6.0_26-b03-384-10M3425)
> Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02-384, mixed mode)
> Reporter: Tsuyoshi Ito
> Priority: Critical
> Attachments: refreshes.png, renderingservice.zip
>
>
> Updating a bundle which provides a WebrenderingService causes an update of
> all bundles (after refresh). Even thougth there are no dependencies between
> most of the bundles.
> test bundles to reproduce the bug attached.
> How to reproduce it:
> parent version 0.3-incubating-SNAPSHOT is used in test bundles (probably you
> need 0.2-incubating-SNAPSHOT).
> attempt 1
> 1. Install and start bundle org.clerezza.app.webrenderingservice
> 2. Install and start bundle org.clerezza.app.webrenderingserviceconsumer
> 3. Go to http://localhost:8080/admin/renderingtest, The WebrenderingService
> produces the text "hello test". WebrenderingService is used in an ssp in the
> webrenderingserviceconsumer bundle
> 4. update org.clerezza.app.webrenderingservice,
> 5. enter ":f refresh", a refresh is necessary. all bundles are updated
> Furthermore the following error occured, which makes Clerezza Console
> unavailable.

> 2. enter refresh => no refresh necessary
