I can't open LibreOffice anymore, neither Writer nor Calc.

1. If I try it from the launcher, the icons flash a few times and then
   stop. The LibreOffice start window emerges for about one second and
   then disappears.


2. If I open Nautilus and click on any document assigned to
   LibreOffice, the LibreOffice start window emerges for about one
   second and then disappears.



3. When trying it from the terminal with libreoffice --writer, for
   example, I see the same behavior and the following error message:

   
   
   

   [Java framework] Error in function createSettingsDocument (elements.cxx).
   
   javaldx failed! 
   
   Warning: failed to read path from javaldx
   
   terminate called after throwing an instance of 'com::sun::star::uno::RuntimeException'
   
   

What can I do?
