AspectJWeaver with JDK 7 - error - only supported at Java 5 compliance level or above

I came across this problem with an older project - when I switched from jdk6 to jdk7, when the application started I encountered: nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.transaction.annotation.AnnotationTransactionAttributeSource#0': Initialization of bean failed; nested exception is java.lang.IllegalArgumentException:   error annotation type patterns are only supported at Java 5 compliance level or above I didn't want a purely maven solution because during development I run the app in Tomcat via the IDE (Intellij IDEA).

Now, when introducing Spring into the mix there are a couple of extra things to do . I came unstuck though because I was trying to do Transactional tests - since I'm now using @RunWith(Parameterized.class) and setting up my Spring TestContextManager manually the @Transaction annotations caused an exception: java.lang.IllegalArgumentException: Superclass has no null constructors but no arguments were given I couldn't find any built in solution, so I've gone with manual transaction management in my test, using doInTransaction: @RunWith(Parameterized.class) @ContextConfiguration(locations = "classpath*:/testContext.xml") public class MyTest { @Autowired PlatformTransactionManager transactionManager; private TestContextManager testContextManager; public MyTest (... parameters for test) { // store parameters in instance v...
