Currently the server is unable to load changed .class files in most projects. I believe only Seam projects can quickly reload seam projects. This is not a tooling issue primarily but is more a runtime issue.
I've considered adding a workspace setting to allow (or disallow) touching of xml files when a .class file is changed, but so far I haven't moved on this issue because demand really isn't that huge for it.
I probably should just make 'restart' go through and touch all descriptors.
