When opening a spreadsheet with a large number of redundant columns (like the truly pathological .xlsx files generated by the AWS Marketplace's product load form), the Apache zip library will throw:
ERROR StatusLogger Log4j2 could not find a logging implementation. Please add log4j-core to the classpath. Using SimpleLogger to log to the console...
Execution error (IOException) at org.apache.poi.openxml4j.util.ZipArchiveThresholdInputStream/checkThreshold (ZipArchiveThresholdInputStream.java:143).
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.

I've been poking around in the code a bit, but I can't figure out how to actually thread ZipSecureFile.setMinInflateRatio() down through Docjure's API. If you have any ideas, I'm all ears! Here's an example file that'll reproduce the error.
