I've got a Spring Boot application deployed onto a Tomcat 6 Server which is returning the following error
org.springframework.beans.factory.BeanCreationException: Error creating bean
with name 'entityManagerFactory' defined in class path resource [com/myApp/PersistenceJPAConfig.class]:
Invocation of init method failed; nested exception is
java.lang.UnsupportedClassVersionError:
javax/transaction/SystemException :
Unsupported major.minor version 51.0 (unable to load class javax.transaction.SystemException)

I know this translates to "you can't run apps compiled with JRE 1.7 on this container", however my project is indeed compiled with the JRE 1.6 runtime and I've tested the app locally on my own Tomcat 6 container with no issue.
I've followed the directions here to get my application Servlet-2.5 compliant: http://docs.spring.io/spring-boot/docs/current/reference/html/howto-traditional-deployment.html
Here's my PersistenceConfig.xml LocalEntityManager config which is returned with the error:
@Configuration
@EnableTransactionManagement
@EnableJpaRepositories("com.myapp.repositories")
@PropertySource("classpath:application.properties")
public class PersistenceJPAConfig{
@Autowired
private Environment environment;
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
em.setDataSource(dataSource());
em.setPackagesToScan(new String[] { "com.myapp" });
JpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
em.setJpaVendorAdapter(vendorAdapter);
em.setJpaProperties(additionalProperties());
return em;
}

Might there be anything I'm overlooking between my local server and deploying the packaged war file? I can't figure out why my project is holding onto any 1.7 dependencies.
