Re: [aspectj-users] Issues with @DeclareParents and @DeclareMixin

Some very odd behavior indeed.  See below for comments

This sounds fishy, but I'll let Andy speak to this.

@DeclareMixin was introduced in 1.6.4, so it looks like here you are
building against the 1.6.4 runtime jar, but compiling with the 1.6.3
weaver that doesn't understand about DeclareMixin.  But I can't say
how this could have happened.

This is odd.  I won't be able to try this out until tomorrow, but it
will help if you can tell me what version of Eclipse / AJDT you are
using.

Also, are you getting a compiler error or an editor error (ie- is it
appearing in the editor only, or does it also appear in the problems
view)?
