That’s an interesting requirement. I don’t know of others doing that but it
isn’t totally unreasonable. I’ve normally used jarjar to move packages, I
wonder if there is a variant of that tool which also allows string replacement.
It seems reasonably robust to modify Lorg/aspectj/lang prefixed strings to
Lshadow/org/aspectj/lang in addition to moving the packages. That would
probably get you a long way, and if there were any remaining issues we could
modify aspectj to make it behave.
In the back of my mind I am concerned about code that is affected by
differently packaged weavers and them maybe tripping each other up, but right
now I can’t think of concrete situations that will fail.
