> It would be a nice feature if ZipFile had support for detecting Zip Bombs.
> Apache Poi has an implementation based on the java util ZipFile but this relies on Reflection and changes in Java 10 mean this code will not work in that version.
> [https://github.com/apache/poi/blob/trunk/src/ooxml/java/org/apache/poi/openxml4j/util/ZipSecureFile.java]
> One option would be to add equivalent change support in commons-compress and for Poi to use the commons version.
