Port Range Limitation in 19c when assigning ACL via dbms_network_acl_admin.assign_acl

Hi All,

We're doing some upograde testing in Oracle 19.3 on RHel7. We're going to it straight from 11.2.4 and we're hitting an issue when creating acceess control lists, ACL. Previously, we would assgn a particular rule with a range of lower => 80  and higher => 65535. In 11.2.4 this all works without issue.

However it doesn't appear to work in 19.3, the spread between lower and upper is much smaller but I can't find any mention of a limitation in the documentation: https://docs.oracle.com/en/database/oracle/oracle-database/19/arpls/DBMS_NETWORK_ACL_ADMIN.html

An example of a smaller spread in 19.3:

SQL> exec DBMS_NETWORK_ACL_ADMIN.CREATE_ACL('DUMMY.xml', 'Allow  network access', 'USERA', TRUE, 'connect');
