I looked at the changes to the manifest code and I think they are okay. 
I don't have time to study the tests in detail.

I think it would be useful to copy the clarification note "(there must 
be a colon and a SPACE after the name)" from the JAR file spec to the 
equivalent sentence in the Attributes class description. That will help 
anyone wondering why the limit is 70 rather than 72. This change 
shouldn't need a CSR as it's not adding any new assertions.
