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

But these 2000 xml files may be relevant! 
You wrote that in values in the map are instances of org.jboss.tools.jst.web.kb.internal.XmlContextImpl, objects of this class are created for xml files; while for xhtml files, it is org.jboss.tools.jst.web.kb.internal.FaceletPageContextImpl
If your xml files are located under a Java source folder, or Web content folder, they are certainly processed by KB builder, which assumes that any xml may contain expression language to be validated.

> I have huge memory problems and two days ago i made a heap dump and got following information:
> The classloader/component "org.jboss.tools.jst.web.kb" occupies 485,306,072 (76.24%) bytes. The memory is accumulated in one instance of "java.util.HashMap$Entry[]" loaded by "<system class loader>".

> It is full of HashMapentries:
> key: org.eclipse.core.internal.resources.File
