Deadlock in com.thoughtworks.xstream.mapper.AnnotationMapper when Jenkins loads folders (see thread dump fragment, "www", "mobile" and "admin"are Jenkins folders).

Deadlock occur systematically when the stdout and stderr are routed to the shell console. The workaround is to route stdout and stderr to a file.

Attached:

jenkins-startup.log: jenkins stdout & stderr
