json builder processes binary data differently from JsonObject class

Version

Vert.x 4.1.0, Kotlin 1.5.10, JDK 16.0.1

Context

It seems that the json builder uses a Base64 algorithm that is different from the one used in the JsonObject itself, and it leads to problems when used with MongoClient (

Steps to reproduce

val binaryValue = byteArrayOf(58, -104, 93, -89, 79, -30, 37, -78, 4, 92, 23, 45, 107, -45, -112, -67, -123, 95,
    8, 110, 62, -99, 82, 91, 70, -65, -30, 69, 17, 67, 21, 50)

val jsonObject1 = JsonObject()
    .put("myValue", binaryValue)

val jsonObject2 = json {
    obj(
        "myValue" to binaryValue
    )
}

println(jsonObject1)
println(jsonObject2)

The output is:

{"myValue":"Ophdp0_iJbIEXBcta9OQvYVfCG4-nVJbRr_iRRFDFTI"}
{"myValue":"Ophdp0/iJbIEXBcta9OQvYVfCG4+nVJbRr/iRRFDFTI="}

The first approach works with MongoClient.insert() just fine. The second one (with json builder) fails if the final Base64 data contains slashes with this exception:
