[aspectj-users] AspectJ Compiler 1.8.10 errors out on wrong classpath

[thofmann <email@xxxxxxxxxxxxxxxxx>]

Hi everyone,

I am trying to migrate an old PDE Build to a newer version of Eclipse, AJDT
and thus AJC. Up until now the build used AJDT 1.6.x and the Java Source and
Target Level was set to 1.6.
The project should now be switched to used Java 8.

I upgraded Eclipse to 4.6.3 and AJDT to 2.2.4.201703272045. When the PDE
build now tries to build a project with aspects it errors out with errors
like this:

These classpath entries really do not exist. The problem is that they are
set in the build.xml file for the project that gets generated from the PDE
build. 

I already debugged the PDE build build file generation. There are no options
that I can use to not generate these classpath entries.

This was no problem before. So my question now is 
a) is there some way that I can tell AJC not to complain about missing
classpath entries?
b) Why was this behavior changed and when?
c) Is this a bug in AJC?

I found this bug but no further information:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=37383

I find it strange that I cannot find more information about this issue but
it might well be that PDE Build with AspectJ is not really in use that
much...

Thanks you in advance,

Thomas
