Spring PropertyPlaceholderConfigurer failed for 2 dataSources - mysql

Question

Spring 3.2.3 PropertyPlaceholderConfigurer failed to init 2 dataSorces.
For single one it works perfectly, but when I delete comments from the second one "rbmDataSource", it fails.
I can't understand why?
database.properties file
db.driver=com.mysql.jdbc.Driver
db.url=jdbc:mysql://localhost:3306/db
db.username=root
db.password=
management.db.driver=com.mysql.jdbc.Driver
management.db.url=jdbc:mysql://localhost:3306/db_management
management.db.username=root
