----------------------------------------------------------------
I have been debugging the issue.
The cascade of refreshes occurs because after compiling the SSP that binds the
webrenderingservice, there is a runtime package dependency of
org.apache.clerezza.scala.scripting on
org.apache.clerezza.org.clerezza.app.webrenderingservice. Note the direction of
the dependency. Something in the Scala Scripting bundle depends on the
Webrenderingservice implementations. Then all bundles dependending on the scala
scripting bundle (contains the Scala compiler service) will refresh as well,
which includes the scala shell, bundledevtool, etc.
I have reduced the files supplied by Tsuy to the minimum in order to reproduce
this issue. In my version 22 dependencies are refreshed (not all bundles).
I still need to locate the exact reason for the dependency.

> 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.

> 1 .Update bundle org.clerezza.app.webrenderingservice again without visiting

> 2. enter refresh => no refresh necessary
