PDFBox failed to rasterize PDF pages with JPEG2000-encoded image streams, logging "Cannot read JPEG2000 image: Java Advanced Imaging (JAI) Image I/O Tools are not installed" and skipping OCR on those pages. Drop the jai-imageio-core and jai-imageio-jpeg2000 JARs into /tika-extras/, which the apache/tika base image already includes on the server classpath, so the J2KImageReaderSpi is auto-discovered via the ImageIO ServiceLoader.
