I've seen this a few times with 7294. While editing a spring xml file that contains various <aop:*> elements, the resolving of Java types in pointcut language (packages, classes) switches from resolving in current project to resolving in another project that I had open. For example, in one case I had a project open that used spring facet, and another project open that contained a plugin module. At some point during editing, the project using spring started to resolve Java types in pointcut lanuage using the classpath of the other project: I would get package completion variants for com.intellij. etc. When closing the plugin project, the project using spring would start throwing "Already disposed" exceptions (all submitted). Perhaps some kind of data race?
