--------------------------------
Assignee: Daniel Kulp
> AbstractTransportFactory registers itself as extension, before being fully
> initialized
> --------------------------------------------------------------------------------------
>
> Key: CXF-4066
> URL: https://issues.apache.org/jira/browse/CXF-4066
> Project: CXF
> Issue Type: Bug
> Affects Versions: 2.4.5, 2.5.2
> Reporter: Vitaliy Garnashevich
> Assignee: Daniel Kulp
>
> AbstractTransportFactory calls register() at the end of its constructor, to
> register itself as a DestinationFactory and/or as a ConduitInitiator. Classes
> that extend AbstractTransportFactory (e.g. HTTPTransportFactory), and which
> call super's constructor, have no way to properly initialize, before being
> exposed as an extension. Such classes must call super() constructor, before
> initializing their fields.
> This could lead to concurrency issues, when such object is used as an
> extension, before being fully initialized. Here is a stack trace of such
> problem:
> java.lang.NullPointerException
> at

> Here, the HTTPTransportFactory.getDestination() method, implementing
> DestinationFactory interface, is called before HTTPTransportFactory's
> "registry" field is assigned by constructor.
