> After a certain investigation, the conclusion is made that the issue is connected to
the <container>/etc/host.key file, which seems to be generated different under IBM JVM
comparing to the one received on Sun Java VM:
> ls -al host*
> rw-rr- 1 root root 1202 2012-04-25 13:03 host.key.sunjvm
> rw-rr- 1 root root 2581 2012-04-25 12:35 host.key
> #
> (see the difference in size, at least)
> If I replace it with a copy of host.key file taken from a different container working
under Sun JVM, everything works just fine.
> The issue reproduces both, with client script running locally and with a remote one running
on Sun Java VM 1.6.0_30.
