actual_tessdata_num_entries_ <= TESSDATA_NUM_ENTRIES:Error:Assert failed:in file .\tessdatamanager.cpp, line 55
Java Result: 1

Answer 1

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.
