[CRIU] Name resolved on unconnected socket

I am executing a Java-based middleware and trying to dump the processes.
However I am having some problems with sockets.
The middleware tries to connect to a maven repository to download the
dependencies and so on.
The problem is that I cannot dump the middleware:
I get the error: Name resolved on unconnected socket.
I checked in the source code and it seems that you don't accept a socket if
it has a name and it is not connected. I don't know how a socket may have a
name without being connected. It happens when sockets are in CLOSE_WAIT
state???? If Yes, shouldn't CRIU be capable of dumping such processes???
Isn't the connection close??? How can I know if the problem is with
ESTABLISH, CLOSE_WAIT or the unix socket???
