Tabela usuario não existe

Olá pessoal,

Estou com um problema aqui, estou usando o Spring 2.5 e esta configurado no arquivo properties a configuração spring.jpa.defer-datasource-initialization=true mas mesmo com esta configuração estou tomando o erro:

Caused by: org.h2.jdbc.JdbcSQLSyntaxErrorException: Table "USUARIO" not found; SQL statement:
INSERT INTO USUARIO(nome, email, senha) VALUES('Aluno', 'aluno@email.com', '123456') [42102-200]

Me parece que não foi inicializado as tabelas antes.

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSourceScriptDatabaseInitializer' defined in class path resource [org/springframework/boot/autoconfigure/sql/init/DataSourceInitializationConfiguration.class]: Invocation of init method failed; nested exception is org.springframework.jdbc.datasource.init.ScriptStatementFailedException: Failed to execute SQL script statement #1 of URL [file:/home/vrn/Downloads/forum/target/classes/data.sql]: INSERT INTO USUARIO(nome, email, senha) VALUES('Aluno', 'aluno@email.com', '123456'); nested exception is org.h2.jdbc.JdbcSQLSyntaxErrorException: Table "USUARIO" not found; SQL statement:
INSERT INTO USUARIO(nome, email, senha) VALUES('Aluno', 'aluno@email.com', '123456') [42102-200]

Arquivo properties:

# datasource 
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.url=jdbc:h2:mem:alura-forum
spring.datasource.username=sa
spring.datasource.password=

# jpa 
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect
spring.jpa.hibernate.ddl-auto=update

# Nova propriedade a partir da versao 2.5 do Spring Boot:
spring.jpa.defer-datasource-initialization=true
spring.jpa.show-sql=true

# h2
spring.h2.console.enabled=true
spring.h2.console.path=/h2-console
