Hi everyone,

I upgraded Apache POI to use the latest commons-compress 1.26.0 release. POI 
processes Microsoft format files like xlsx and docs files - these formats are 
basically zip files with XML and other files contained within.

The issue seems to be that commons-compress 1.26.0 requires signatures.

We get exceptions like this:

java.util.zip.ZipException: Cannot find zip signature within the file

Most of the test files that have were created by Excel or Word or Powerpoint.

Is there a way to disable this zip signature check? Any advice would be 
appreciated.

Regards,
PJ
