Imagine this code:

public class Main \{ // tc root private final HashMap<String, T> root = new HashMap<String, T>();

public void put(T t)
  Main<Main> main = new Main<Main>();
  main.put("foo", main);       
public String get() 
    Main<String> main = new Main<String>();
     return main.get("foo");
}  \}

Now imagine running this in one node calling put. This would allow you to put objects of type “Main” into the datastructure held by the root. Calling “get” on the other node will result in a runtime class cast exception.

Not nice.

Do you have a proposal of how this should be fixed? It’s a little late for us to influence sun’s decision to use erasure

Create a related doc issue to add to gotcha’s

Is there a workaround? What is the proper description of the issue for documentation purposes:?
