lsp4e: ClassCastException

See original GitHub issue

When opening an xhtml-file (for JSF), then Eclipse throws nearly every few seconds (as long as this file is opened) this stacktrace:

When saving the xhtml-file, I also get this error:

An internal error occurred during: "Refreshing JSF information about: L/myproj/src/main/webapp/WEB-INF/jsf/users.xhtml".
Cannot invoke "org.eclipse.core.runtime.IPath.segment(int)" because "fullPath" is null

Is that because of wwd?
