["Tom Watson (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FELIX-6552?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17573752#comment-17573752 ] 

Tom Watson commented on FELIX-6552:
-----------------------------------

An error should have been logged with the LogService, but the service component must not be prevented from being activated according to the specification:  https://docs.osgi.org/specification/osgi.cmpn/8.0.0/service.component.html#service.component-binding.services

>          Issue Type: Bug
>          Components: Declarative Services (SCR)
>            Reporter: Christoph Läubrich
>            Priority: Major

> I recently found a very strange behavior with one of my components:
>  # there is a static bound setter for a service X
>  # in case of injection of X I call a method an perform some action on it
>  # if it now happens that a ClassCastException is thrown this seems to be silently ignored
>  # my activate method is called and the service seems to be registered sucessfully
> This is very bad, because I only noticed that something was wrong because it failed then later on and everything looks "normal" (no entry in the OSGi log for example, component seems to be activated...)
