hi.

after using the adjt plugin, i see from time to time, pressing right click on a project or moving from eclipse window and back to it, causes eclipse to have huge amount of time for garbage collection, why is that?

Do you notice this only for AJDT projects, or are all projects affected?

AJDT does use a fair amount of memory for keeping the crosscutting model available. Perhaps this is something that is causing your extra GCs. Do you have many large aspectj projects?

There are several things you can do:

1. Show the heap status of your Eclipse. This can tell you how much memory you are using and when GCs happen.

2. We are actively working on reducing the memory of AJDT. See: https://bugs.eclipse.org/bugs/show_bug.cgi?id=278496

To use the advanced memory features described there, you can add the following system properties to the command line used to start eclipse: -Daspectj.minimalModel=true -Daspectj.typeDemotion=true

These are still experimental options (read the bug report). Please let us know if they address any of your memory issues.
