FAILURE: See Problems View. There are four warning messages instead of the only one.

I see there at lease two problems. First at all it seems that EclipseUIUtil.isOpenInActiveEditor(IFile) doesn't work anymore. It returns false for any file even if it is open in an active editor. So we use the cached page context of the file when we are editing it. This is a bug.
Second issue is that our PageContextFactory returns a context with many duplicated EL references for the same EL. It causes multiple problem markers for the same EL.
