Hi,

I think this is your JVM having trouble with the IPv6 java issue.

Try to start eclipse with the following options:
 -vmargs -Djava.net.preferIPv4Stack=true

Both must be present and the order is significant (eclipse ignores
arguments it does not understand, so it will not error out if it is done
wrong).
  Alternatively you can add -Djava.net.preferIPv4Stack=true on its own
line in the config.ini file after the -vmargs line (requires root
permission).

Note: This workaround is tested with openjdk-6. For sun-java6 you may
have to use the workaround described in #560056 and gcj is generally not
supported for running eclipse.

You may also find [1] interesting.
