The problem is a type mismatch ... the operation is declared for
'scala.math.BigInt', but you're trying to use it as a
'java.lang.BigInteger'. There should be no problem with consistently
using the former even in Java code, since the conversion is trivial:

  scalaBigInt.bigInteger() // returns Java BigInteger
  new scala.math.BigInt(javaBigInt) // constructs Scala BigInt
