Ah yes, the joys of AOT-compilation and static initializers. I know them
well.
Strange things happen with AOT-compilation. Classes get loaded in a
different order, or get loaded by different classloaders. Maybe someday we
can figure it all out. Try replacing that with `instance?` as you say. (Is
the return value of `defrecord` even defined?)
If nothing else works, it is possible to disable AOT-compilation
altogether. The Contrib super-POM does it only as a sanity check.
I tried this and got failures during the test phase:
[INFO] --- clojure-maven-plugin:1.3.13:test (clojure-test) @ core.typed ---
Exception in thread "main" java.lang.StringIndexOutOfBoundsException:
String index out of range: 1,

at clojure.lang.Compiler.analyzeSeq(Compiler.java:6567)
