Hey,
First I’d say try it on 1.9.2 as that includes an updated Eclipse JDT. I
recall fixing something around source location lookups in 1.9.2, but can’t
recall if it was for fields or not, might have been just types and the fix
needs extending to fields. As it stands when I look at 1.9.1, line 425 isn’t a
line that can NPE so an updated position for 1.9.2 would be nice. Feel free to
raise a bug at https://bugs.eclipse.org/bugs/enter_bug.cgi?product=AspectJ
That APT area is somewhat limited in test coverage, so I’m not surprised to hit
some things if dabbling in that area.
cheers
Andy
