Alessio Soldano resolved CXF-3634.
----------------------------------
Resolution: Fixed
> Avoid risk of deadlock and speed up execution in JDKBugHacks.doHacks()
> ----------------------------------------------------------------------
>
> Key: CXF-3634
> URL: https://issues.apache.org/jira/browse/CXF-3634
> Project: CXF
> Issue Type: Improvement
> Components: Core
> Reporter: Alessio Soldano
> Assignee: Alessio Soldano
> Fix For: 2.4.2, 2.5
>
>
> In order for disabling url caching, JDKBugHacks runs:
> URL url = new URL("jar:file://dummy.jar!/");
> URLConnection uConn = url.openConnection();
> uConn.setDefaultUseCaches(false);
> When having the java.protocol.handler.pkgs system property set, that can lead
> to deadlocks between the system classloader and the file protocol Handler in
> particular situations (for instance if the file protocol URLStreamHandler is
> a signleton).
> Besides that, the code above is really there for the sake of setting
> defaultUseCaches to false only, so actually opening a connection can be
> avoided, to speed up the execution.
