Comment lines have not been filtered out when the populate_global_dict function parsed install.properties in security-admin/scripts/db_setup.py. So if we use '#' to comment a line and it includes '=', the comment will not work. On the left of the '=', it will be parsed as a key and the right will be parsed as a value. As a result, there are two problems as follows:
1. There are invalid attribute values in globalDict variable.
2. Invalid parsing will degrade the performance of program.
