Guillaume Nodet commented on MCOMPILER-368:
-------------------------------------------
It's unrelated to MSHARED-763. The actual problem is that no file is generated
by default for {{package-info.java}} files that only contain some javadoc and
those are later detected as stale, as if the corresponding
{{package-info.class}} would have been deleted.
We need to somehow record the fact that the compiler did not produce any output
for some files.
