Bug#1074355: libmina-sshd-java: FTBFS more than 50% of the time

[Santiago Vila]

Note: It is possible and likely that the reason it fails for me
is different than the reason in the original report,
i.e. java.io.IOException: Mount point not found.

For simplicity I decided to raise this one because it FTBFS
consistently for me. I will be happy to provide more feedback
if a partial fix (i.e. fixing only one of several detected bugs)
is uploaded.

Thanks.
