Errr. If you read the article, his testing was on the allocation side. The collection side was explicitly called out as a non-issue.
That said, otherwise you're right that the JVM generally makes use of the generational hypothesis depending on the collector. The Gen 0 is referred to as Eden in Java-land and uses thread-local allocation buffers that just bump pointers to allocate. They're basically just like arena allocation.
