Re: [ajdt-dev] Problem when weaving aspects boxed in a jar file
|
This problem occurs if the compiler sees an 'old' format version of an
aspect. Are you *definetly* using the same version of AspectJ/AJDT
when going through this sequence?
Normally it occurs because some aspect has been built with compiler
version 'A' and then binary weaving is attempted (eg. using aspect
path) with compiler version 'B' - because 'A' wrote out the pointcut
attribute in an older style, compiler 'B' chokes on it when it sees
it. This is happening a lot lately because we are working on Java5
language features which are causing us to constantly change the format
of the attributes - there is no guarantee that two dev builds of
AspectJ5 will be compatible. The only thing we are trying to
guarantee right now is that the final version of AspectJ5 will be able
to understand AspectJ 1.2.1 built code.
