Cannot invoke "clojure.lang.Var.isBound()" because "clojure.lang.Compiler.LOADER" is null

Failed generating 'native-test' after 5.0s.

It seems the number of threads set to high number also increases the chance of getting this error. From time to time the analysis can also fail.

The detailed reproduction might be found here
