The following workaround has been posted on the Jira and is known to be working:
To perform an upgrade (3.4 -> 3.5):
- download the "snapshot.0" file attached (to the Jira)
- copy it to the versioned directory (e.g. "version-2") within your data directory (parameter "dataDir" in your config - this is the directory containing the "myid" file for a peer)
- restart the peer
- upgrade the peer (this can be combined with the above step if you like)
