control panel shows two values of one boolean property, it makes the property invalid and makes it into false.
in portal-ext.properties file.
2) start portal, go to control panel -> server administration -> Properties -> Portal Properties, find theme.css.fast.load
expect result: the value should be "true" or "false"
actual result: the value is "true,true"
"true,true" does not equal with "true", so the value means "false". It is against portal-ext settings.
