I'll answer myself:
it's mandatory to use "src/main/resources/" as the base folder inside
KieFilesystem.
kieFileSystem.write( "src/main/resources/" + fileName,
kieServices.getResources().newInputStreamResource( is ) );
with fileName = "etc/MailFilter.xls".
Now Apache POI breaks down processing my xls file which works with
drools 5.5 / JExcelApi:

Hello,
I need your help!
I'm trying to migrate from Drools 5.5.0 to 6.0.1, creating the
KnowledgeBase programmatically.
But buildAll gives me WARN "No files found for KieBase defaultKieBase".
What's missing? My code is based on the example found in documentation.
fileName is pointing to an xls file with decision table.
Writing it to kieFileSystem seemed to work correct, as
kieFileSystem.read( fileName ).length is showing the right number of bytes.
