[wtp-dev] Helo with Egit error when accessing a repo using ssh

[Roberto Sanchez Herrera/Mexico/IBM <rsanchez@xxxxxxxxxxx>]

Hello, this question is not specific to
WTP, but I wanted to try asking here, since Egit is used among WTP contributors.

Since last week, when I try to pull
or push to any of the webtools repository for which I'm commiter using
Egit, I get this error:

org.eclipse.jgit.api.errors.TransportException:

Has anybody else seen this error? Any
advice/suggestion?

I know there were changes in the eclipse.org
keys, so I updated the contents of my known_hosts file, but I still see
the same error. 

Pushing/pulling works fine if I use
git command line.

I'm using Egit 3.7.0.201502260915-r,
and I have tried different versions of Java 7 and 8, and different vendors.
