I've got similar problem in Java + Servicemix/Camel. Error is thrown from net.sourceforge.tess4j.util.ImageIOHelper. The class is trying to collect something image readers/writers by image type. So from line #100 "Unsupported image format." is thrown if there was not any reader found for the image type (for me - if I trying to open tiff). The magic "Need to install JAI Image I/O package" is thrown not because there is no jar available the reason is different and the library is in place. Any image...
