Tsuyoshi Ito commented on CLEREZZA-617:
---------------------------------------

When not casting the service object to the actual Class T no refresh is necessary. I was not aware that using "(T) bundleContext.getService(serviceReference)" forces a refresh when updating the bundle which contains the service object.

> 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.

> Because Clerezza Console is unavailable I have used http://localhost:8080/system/console/shell 
> attempt 2
> 1 .Update bundle org.clerezza.app.webrenderingservice again without visiting http://localhost:8080/admin/renderingtest first (not compiling the ssp)
> 2. enter refresh => no refresh necessary
