Critical Description
The error appears sometimes when I try to open or close faces-config.xml and Studio proposes to exit. If I choose exit, than this workspace cannot be opened anymore and Studio fails to start.
I do not know any reproducible way to catch this error, but it appears several times a day in my workspace that has two JSF projects in it.
