Just to explain one more piece of the
puzzle: the reason that AJDT (and also AJBrowser) use more memory is that
in addition to the straight compilation they also build and retain an in-memory
structure model for the program - including all the advice relationships
etc..

Hi Ron -

You might be right about the size of the project.
Also try building with ajbrowser.  The implementation
stack is something like this (view with constant-width
font):

   ajc             ant    
     ajbrowser      ajdt
   ---             ---    
     ---------      ----
                   AjcTask
   ajbrowser.Main   AJDT
   ajc. Main       ajc.Main   AJDE    
        AJDE
   AjdtCommand     {same..}   CompilerAdapter  {same..}
   AjBuildManager             AjBuildManager

So if it works from the command line and Ant but not
ajbrowser or AJDT, then the problem is probably in AJDE
or CompilerAdapter.  If it works in ajbrowser also,
then the problem is probably in AJDT or eclipse -- which
I doubt, since AJDT mostly just passes the config file
to AJDE.  If the problem shows up in ajbrowser, it's
worth submitting a bug to the AspectJ IDE component:

  http://dev.eclipse.org/bugs/enter_bug.cgi?product=AspectJ

P.S. -
I'm sure you've also verified the version of Java is the
same for both Ant and AJDT runs.  For ajc and ajbrowser
scripts, it's the one you installed with.  For Ant, when
running in-process it is the Ant VM, and when forking
it's the one set by the JAVA_HOME environment variable
passed to Ant.  In AJDT I believe it is the eclipse VM
(possibly set using -vm on the command line).  (It's
not a difference that should make a difference, but
when size matters, it seems to.)

P.P.S. - Not sent to ajdt-dev pending their recognition
that I'm a subscriber.
