Problem with JDK 1.4 and tx:advice

[dbrinker]

We're running into some odd problems when trying to build a simple transactional app using Spring 2.0.5 and JDK 1.4.2.

We're trying to use the schema-based tags to set up our AOP and transactions, but whenever we include the tx:advice tag, we get this error:

java.lang.IllegalStateException: Unable to load class [org.springframework.transaction.annotation.AnnotationTransactionAttributeSource]. Are you running on Java 1.5+? Root cause: java.lang.UnsupportedClassVersionError: org/springframework/transaction/annotation/AnnotationTransactionAttributeSource (Unsupported major.minor version 49.0)

For reference, our config file is below.

As you can see, we're not using <tx:annotation-driven> or anything similar that requires JDK 1.5. Has anyone run into this before, and if so, how did you get around it?

Thanks

Obivously if you were using @Transactional the exception would make sense. As you're not it looks like a limitation or bug. I'd have a look in JIRA and see if anyone else has raised a similar issue.

In the stacktrace you should see where AnnotationTransactionAttributeSource is trying to be loaded - that's probably the point of error. This class seems to be 1.5 compiled (for a more or less obvious reason).

Was there any follow up to this?

I haven't found anything in JIRA. I *am* wondering if this isn't due to the fact that I'm including the <tx:advice> without providing any <tx:attribute> definitions. I should be able to test that out today...
