    The error happens because the C++ code throws an exception. Java can’t “wrap” those.

    The exception is thrown because the following assertion is violated:

    actual_tessdata_num_entries_ <= TESSDATA_NUM_ENTRIES

    The constant is defined in tessdatamanager.h. It’s related to the data files which you need. Make sure the data files you use match your version of tesseract.
