Viacheslav Kabanovich commented on JBIDE-11539:
-----------------------------------------------

Yes, it is srange to have thousands of entries in PageContextFactory.cache map, if your project has just a couple hundred of files. We have to know what kind of 'extra' source finds its way into the map. Could you please count all xml/html/xhtml/jsp files in your workspace? Also, does your project have links, either to external resources, or referencing inner resources by a different path?
