Affects versions: Release 1.8
Fix versions: None
- AOT compile all the namespaces in clojure/tools.logging (clojure.tools.logging & clojure.tools.logging.impl)
- With the result on the classpath, AOT compile clojure/java.data (clojure.java.data)
- Observe `clojure/tools/logging$eval32$fn__33.class` in the output of the second compile (make sure to have different output directories for the two compiles).
This is normally harmless, but becomes an issue if you try to cache AOT compilation output. When you try to cache previous AOT runs this way, you sometimes end up with two otherwise unrelated namespaces generating the same filename. If these had the same contents that would be fine, but there's no guarantee that they have the same contents (since 32 & 33 there are just (gensym)s). Depending on which one "wins" in a classpath this could end badly.
I'm not an expert here, but it would be nice if these "extras" were either generated as part of tools.logging or were somehow aliased into the namespace they were compiled from (e.g. clojure/java/data/$clojure$tools$logging$eval32$fn__33.class or clojure/tools/logging/$clojure$java$data$eval32$fn_33.class).
