Happy new year!

Just wanted to report a minor bug I've encountered while working on F4 issue. The icons pod has no types, so compiler::FPod#read fails with NPE while trying to read data from /fcode/types.def. This causes an issue in F4, but can be reproduced in a console build when build.fan sets build::BuildPod#dependsDir:

Hi Ivan,

I'm trying to reproduce that problem, but can't figure it out (at least in latest code). I added a dependency on icons pod and did various things like introduce compiler errors.

Hi Brian,

Thanks for looking into that. I've uploaded a sample project here – http://iinozemtsev.net/dump/issue38.zip

It's really just a single empty class, even without compile error, and almost default build.fan with a dependency to icons pod. It compiles fine via fan build.fan, but once I specify dependsDir in build.fan, this error happens, as it seems that compiler starts using FPods instead of ReflectPods.

Thanks for reporting that. I pushed a fix.
