New Revision: 895971
URL: http://svn.apache.org/viewvc?rev=895971&view=rev
Log:
Fix issue FELIX-1965
When a validate callback throws an exception, the service is still published (a
small amount of time). This 'door' allows a consumer to use a non initialized
service.
The fix avoids that and test it.
