Hi,
It's helpful to consider the Core and UI parts of JDT separately. JDT-Core
is essentially the Java compiler, and JDT-UI is the user interface support
for working with Java in Eclipse. The AspectJ compiler is the equivalent
of JDT-Core, and that does duplicate the JDT-Core code and extend it as
required. The changes are synchronised with the latest JDT-Core sources as
and when required. Some of the extensions are now implemented with
aspects, which will help the move up to future JDT-Core versions. The AJDT
plugin is the equivalent of JDT-UI, and that does *not* copy and extend
the JDT-UI code. We did try that but it proved difficult managing the
resultant contributions to Eclipse - e.g. you could end up with a project
containing two different instances of Java classes, which weren't
compatible with each. So the current approach in AJDT is to extend the
existing JDT-UI functionality whenever we can. In a few places where this
isn't possible, we do copy and extend a select few classes from JDT-UI
(and also PDE-UI to add support for AspectJ-enabled plugin projects). See
also the LDT: Language Development Toolkit (website and newsgroup), which
has been proposed as a technology project to look at generalising JDT to
support other languages.
Regards,
Matt.

It's a pity that developers of JDT plugin made it so non extendable. For
example, NetBeans plutform Java plugin is more flexible and we've
succesfully reused the big part of its classes just by extending them (no
code copy) and integrated in NetBeans IDE.
