Matthijs Hendriks commented on AMDATU-517:
------------------------------------------
My findings
* *general remark: the purpose of this bundle is not entirely clear. What
problem does it try to solve that isn't possible with the regular
ExtHttpService of Felix?*
* I honestly do not know.
* *HandlerServletContext has SuppressWarnings("deprecation") for some
deprecated methods?*
* _ExtServletContext_ requires the class to implement these methods. However,
for _ServletContext_, these methods are deprecated (without replacement for
most). I have 'fixed' this by deprecating the methods that function as a
'reference' to the deprecated method and, if possible, replacing deprecated
calls by non-deprecated ones.
* *DispatchInterceptFilter tries to avoid duplicate initializations, but this
is still possible as no synchronization takes place in this method; aside that,
why is this necessary, as the Filter API clearly defines that it will call the
init method exactly once only?*
* You are correct, this check is redundant & broken. I have removed it.
* *DispatchInterceptFilter has an unused method (getLogMessage);*
* It has not in my version.
* *AbstractHandler is not thread-safe wrt its state member;*
* _m_state_ is now volatile, fixing this.
* *DispatcherServiceImpl has redundant service-lifecycle methods & log
statements;*
* I have removed the redundant log statements. I have not found any redundant
service-lifecycle methods.
* *DispatcherServiceImpl#start manually creates HandlerRegistry services which
is feeds OSGi services without respecting their life cycles, make them managed
components by DM should solve this.*
* I might have solved this. Not entirely sure.
A patch/pull request for all this will follow shortly.
