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:
Caused by: java.lang.NullPointerException
