Are there any research jobs in java

Are there any research jobs in java. or companies that work quite in depth with java. how does one detect such companies...generally i have seen many companies will just be writing simple java code and much less using the deeper concepts like multithreading and other things in java. what kind of products will be using deeper concepts.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I am not sure if my definition of "research" is the same as yours, but the only place they are doing research about Java is the JCP (Java Community Process) and Oracle itself, where they research new concepts and define the future of Java. Of course other organisations that have implemented their own JDK are also doing research about Java.

With regards to multi-threading, I am not sure if it is defined as "deeper" concept; for me is just a standard concept. "Deeper" would be if you want to do byte code manipulation for example.

But generally if you want to do SE Java and not JEE you have to look at specific industries. For example banking/finance uses lots of multithreading since they implement their own products to do financial transactions. Gaming (be it gambling or online gaming) also uses lots of the technologies you mention since they also have their own products.
