From memory one of the responses to Liam's reported issues was to document in the release notes what Java 8 is now more strict/correct with regards to badly mixed raw-types?

I changed the bug resolution to "not an issue" because we are in sync 
with the spec. Regarding Liam's issue, yes this issue will be documented 
in the release notes. This will also cover the issue you reported.
