Hi, we use spring-remoting for a Client-Server-Application. Now we are in doubt how to realize a real load test with serialized objects. The problem is that many load testing toolkits are based on plain text HTTP communication, so it's very easy to parameterize the http-requests. Because spring-remoting is based on serialized objects w...

For instance: event is of type Event; date1 and date2 are of type DateTime and also date1.equals(date2); 'events' is my event collection. event.put(date1,...
Consider the following code: for(int i = 0;i < 200;i++) { ArrayList<Integer> currentList = new ArrayList<Integer>() {{ add(i); }}; // do something with currentList } How will Java treat the class of currentList?
