Because LibreOffice is installed with --no-install-recommends, those two X11 libraries were not pulled in transitively, so in non-headless mode loading libawt_xawt.so failed with "UnsatisfiedLinkError: libXtst.so.6: cannot open shared object file", cascading into "NoClassDefFoundError: Could not initialize class javax.imageio.ImageIO" when Solr/Tika indexes image attachments. Installing libxtst6 and libxi6 makes ImageIO work in both headless and non-headless modes.
