[aspectj-users] serialversionuid

[Chris Elgar <chris.elgar@xxxxxxxxxxxxxxxxxxxxx>]

Hi All

I have a question about the following statement in the FAQs (http://www.eclipse.org/aspectj/doc/released/faq.html#q:serialversionuid):

13. How does ajc interact with the serialVersionUID?

The current version of ajc can change the serialVersionUID of generated .class files as a result of weaving in advice. This is an important fact that developers using both aspects and serialization should be aware of. It is likely that a future version of the compiler will be better behaved regarding the serialVersionUID.

However, changes to the serialVersionUID attribute are typically only important when using serialization for the long-term persistence of objects. Using standard Java serialization for long-term persistence has a number of drawbacks and many developers already use alternative solutions. For one possibly standard solution, see Long-Term Persistence for JavaBeans Specification .

Under what circumstances does ajc change this field?

As an example, could adding a logging aspect for a run of a system have the potential to change this field so any objects created when logging was on could be incompatible with the normal Java objects?

Has anyone had any problems as a result of this???

Thanks Chris
