Re: [aspectj-dev] Changing the class hierarchy
|
What constructors are defined in the OntClassImpl class? In order for
the declare parents to succeed, it needs to modify super calls within
any ctors in the targetted class (OntClassImpl). It does a number of
checks to verify what you want to introduce into the hierarchy is
allowed. However, the ability to binary weave declare parents
'extends' is a recent addition to AspectJ (for a long time we only
supported extends if done with all source) - and it looks like you've
found a bug. Is there any way you could do an all source compile and
see what error gets reported?
