Description Juergen Graf CLA 2005-05-27 06:28:47 EDT 
IWorkspaceRoot root = ResourcesPlugin.getWorkspace().getRoot();
  IJavaModel javaModel = AspectJCore.create(root);

throws the following Exception:

Comment 1 Mik Kersten CLA 2005-05-27 11:20:07 EDT 
Matt, I'm assuming that AspectJCore related stuff should go to AJDT.
Comment 2 Andrew Clement CLA 2005-05-27 11:32:01 EDT 
I'm not sure it goes in AJDT - given that AspectJCore is a part of the JDT
compiler code that we provide from the AJ project.  I think Adrian also did a
little bit of work on this a while ago...
Comment 3 Matt Chapman CLA 2005-05-27 11:43:11 EDT 
I think the confusion is that there are two AspectJCores:
org.eclipse.ajdt.core.AspectJCore (AJDT)
and
org.aspectj.ajdt.core.AspectJCore (AspectJ)

Both implement create() but the AJDT one only implements create(String) to
convert a handle identifier into an IJavaElement. So we must be talking about
the AspectJ one, which inherits create(IWorkspaceRoot) from JavaCore
(org.aspectj.org.eclipse.jdt.core.JavaCore that is, not
org.eclipse.jdt.core.JavaCore - confused yet, I know I am!).
Comment 4 Juergen Graf CLA 2005-05-30 11:54:13 EDT 
Calling

org.aspectj.org.eclipse.jdt.internal.core.JavaModelManager.getJavaModelManager();

results in the same exception.
