TC will play funny with Generics
--------------------------------
Key: CDV-516
URL: https://jira.terracotta.org/jira//browse/CDV-516
Project: Community Development
Issue Type: Bug
Reporter: Taylor Gautier
Assignee: Issue Review Board
Imagine this code:
public class Main<T>
{
private final HashMap<String, T> root = new HashMap<String, T>();
public void test()
{
T foo = root.get("bar");
}
public static void main(String[] args)
{
new Main<Main>();
}
}
Now imagine running this in one node like using Main<Main> and another node
with Main<String>. This would allow you to put objects of type "Main" into the
datastructure held by the root. Code on the other node assuming the
datastructure is Main<String> would assume that the cast cast will succeed
because of the compiler constraints, but doing a get will then result in a
String -> Main conversion, causing a runtime class cast.
Not nice.
