Hi All,
I am new to AspectJ and I am using AspectJ1.7 version.

I have some queries regarding version compatibility.

Does AspectJ1.7 is compatible with JDK 1.6? Does AspectJ 1.7 compilers and weavers need JDK 1.7 version or it is supported in JDK1.6 itself.

And the other thing is what new features of AspectJ 1.7 is applicable in JDK 1.6 version.



Thanks,
Jeevitha

Yep. You can use JDK 1.6 with aspectj 1.7. You must set your source and target levels appropriately in order to do this. For example, in Eclipse, you must set your Java compiler compliance level (Perferences -> Java -> Compiler -> JDK Compliance) to 1.6. In this case, however, 1.7 language features will be disabled.

There are quite a few bug fixes and a few smaller features. Check out the readme for the 1.7 release.

http://eclipse.org/aspectj/doc/released/README-170.html

And the best place to ask questions about aspectj is the mailing list.

Hi Andrew!!

May I know what is Bytecode Caching in AspectJ1.7?

And when caching is enabled, what exactly is cached??

What is the life of Caching? Is it automatically refreshed or is Static?

Is there any Memory limit for Caching? ie. If only to certain extent Caching is done or is unlimited??



Thanks,
Jeevitha

Bytecode caching allows the loadtime weaver to weave the bytecode once and then cache the results so that loadtime weaving starts much faster.

I can't tell you much more than that. I'd recommend that you send a message to the aspectj users mailing list, over here:

Andy, the one who implemented the caching is currently on vacation (will return Friday). He should be able to answer then.
