java.io.IOException: Zip bomb detected! The file would exceed the max. ratio of compressed file size to the size of the expanded data.
This may indicate that the file is used to inflate memory usage and thus could pose a security risk.
You can adjust this limit via ZipSecureFile.setMinInflateRatio() if you need to work with files which exceed this limit.
Uncompressed size: 1935318, Raw/compressed size: 19345, ratio: 0.009996
