> It seems to be a problem when creating the classpath. I changed the following
> method in "AbstractAjcMojo"
> protected String createClassPath()
> {
> String cp = new String();
> Set classPathElements = project.getDependencyArtifacts();
> classPathElements.addAll(project.getArtifacts());
> Iterator iter = classPathElements.iterator();
> ...
> }
> Replaced with:
> protected String createClassPath()
> {
> String cp = new String();
> Set classPathElements = Collections.synchronizedSet(new
> TreeSet(project.getDependencyArtifacts()));
> classPathElements.addAll(project.getArtifacts());
> Iterator iter = classPathElements.iterator();
> ...
> }
> This change fixes the problem.
> Seems to me, that multiple threads are accessing the set concurrently.
