My 2 cents:

It's called "binary plugs", which means it's used to provide binaries  
for those components whose sources are not included in the OpenJDK  
yet. So, even today it looks like a full JDK, tomorrow you may see it  
includes only several jars and native libraries, and then one day, it  
will disappear completely.
