Yes, this is absolutely true.
I don't think the impact is as earth-shattering as this description implies.
Note there is a difficult issue in generifying the documents: what syntax will
be used to indicate generic parameters? If we use the obvious source-level
syntax in the documents
that will look like an HTML tag and turn everything italic.
On the other hand, if we use the obvious HTML syntax
then our users will wail and moan. Perhaps we need to invent a compromise
just for javadoc - such as an embedded tag
Then Map<K,Map.Entry<K,V>> will be written
Alternately, perhaps we should stop trying to directly support HTML.
