Interpolation doesn't work in the same resource file.

[SentryMan]

stuff like this doesn't work

database.schema=foobar
database.host=localhost
database.portPrefix=${global.portPrefix}
database.port=${global.portPrefix}5432
database.url=jdbc\:postgresql\://${database.host}\:${database.port}/${database.schema}
database.username=${database.schema}
database.password=${database.schema} 

Funnily enough, it works if you do it programmatically via setProperty. I guess because CoreMap uses a HashMap iterating over it doesn't guarantee that the keys are read and interpolated in the correct order
