See Tika configuration: https://tika.apache.org/1.19.1/gettingstarted.html

And relevant Jira issue: https://issues.apache.org/jira/browse/TIKA-1729

tw4l commented 5 years ago

Issue seems to be with libraries for reading JPEG2000 and TIFF images. See: https://pdfbox.apache.org/2.0/dependencies.html#optional-components

Look into licensing issues before making any changes (these libraries are no longer included with Tika by default due to licensing)
