--- Comment #16 from Axel Howind <[email protected]> --- The result of analysis is that this is not a bug in POI. The files you attached are both valid Excel files and can both be opened without problems using original MS Excel. You have yourself hinted at the apparent cause of the incompatibility with your software: apparently your detection algorithm relies on an undocumented implementation detail, that is the order of zip file entries. That order has been changed to *increase* compatibility with third party software (https://bz.apache.org/bugzilla/show_bug.cgi?id=59747). We will not revert that change as that would mean introducing an incompatibility with a widely used tool for file detection. As has been stated before, the correct approach is to fix the detection algorithm that you are using. As you cannot share the code with us, there is nothing more we can do for you. If you rely on some external library for the detection, please open an issue with that library. If the detection algorithm is developed by your company, you have to fix it yourself. You should be able to get help on stack overflow, but people there will probably request to see your current code as well. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
