That may have used to be true, but with every release of Java the language and standard library grows. More features means simplicity is lost, and Java is huge.
The language hasn't changed very much since inception. Java 8 was probably the biggest of the changes with Lambdas. But even so Java 8 looks a lot like Java 1 at the language level.
The standard library has always been bloated. Hopefully Java 9 and Project Jigsaw will break it up into smaller manageable trunks. Really a lot of it needs to be burned away for new stuff to grow.
The tough part for Java will be when they have to break backwards compatibility to move the language and VM forward. If not done careful they will have another Python 3 on their hands.
