Method code too large! error when feeding BOPP more than 10 priors to sample from

[BorisVSchmid]

I am getting a

clojure.lang.Compiler$CompilerException: java.lang.RuntimeException: Method code too large!, compiling:(C:\Users\Boris\Boris\home\projects\methodlarge\src\methodlarge\core.clj:13:1)

error when feeding BOPP too many priors and a primitive procedure. Here is a minimal example with BOPP 0.1.5 with java version 1.8.0_191, in which the first defopt example spits the method code too large error. The problem doesn't seem to be with anglican, but with BOPP. Is there any way around it?

(ns methodlarge.core
  (:require [bopp.core :refer :all])
  (:require [anglican.core :refer :all])
  (:require [anglican.runtime :refer :all])
  (:require [anglican.emit :refer :all]))

What I can find on the internet, is that some functions in clojure can generate errors like that. See:
