This is not a valid Maven version.
Valid version should be <major>.<minor>.<patch><qualifier> where
major/minor/patch are numerics
We'd probably better follow "plug&pray" development style and go ahead
with jre6/jre7/jre8 then.
Any volunteers to prepare such a PR? (I'm not sure if there's anything
more than mvn versions:set is required)
