class ApplicationNodeDefinition {
      String id;
      String hostName;
      int httpPort;
      ApplicationState state;
      Map properties;

      public ApplicationNodeDefinition(String id, String hostName, int httpPort, ApplicationState defaultApplicationActive, Map properties) {

         this.hostName = hostName;
      }
   }

we observe rather dismal performance while doing operation like:

1. moving the cursor around the id parameter of the constructor: hit the left arrow and wait as much as 10s and watch memory utilization increase by 10MB and then the next arrow hit comes down 10MB again... IDEA is frozen the whole time.
2. Alt-Enter will take usually 5s to show the menu but then needs another 10s to start responding to input. Before that it is frozen as is the whole IDEA frame.
3. clicking in the id param will take a 6-10s full IDE pause (compared to the no delay with any other identifier or the same ctor)

This does not happen is I rename id to anId for example so it has to be related to the fact that id is short and common in our project.

I attached a few cpu snapshots for the diverse pauses I talked about.
