Tomcat Lucce Permission 640 instead of 644

For a project with an upload, I had a permission problem. Lucce set the file permission to 640 after an upload, which in my case led to a „Permission denied“.

I decided to implement the UMASK in Tomcat.

In the file:
/tomcat/bin/catalina.sh

the value:
UMASK="0027"

to:
UMASK="0022"

Tomcat/Lucce writes folders with 755 and files with 644 now.
