MapReference resolver throws java.lang.IndexOutOfBoundsException when trying to round trip to and from file

[amf08006]

Describe the bug
Serializing a simple map to a byte array, persisting to a file, and then reading bytearray back from file fails with IndexOutOfBoundsException

To Reproduce
Steps to reproduce the behavior:
This is an example of a test that reproduces the problem
`
val mapToSerialize = Map("1" -> "Bananna", "2" -> "Apple", "3" -> "Cheese")
val path = Paths.get("/c/temp/testFile.bytes")

val serializedBytes = Base64.getEncoder.encodeToString(ScalaKryoInstantiator.defaultPool.toBytesWithClass(mapToSerialize))
if(!Files.exists(path.getParent)) Files.createDirectories(path.getParent)
val writer = new BufferedWriter(new FileWriter(path.toFile))
writer.write(serializedBytes )
writer.close()

val byteArray = FileUtils.readFileToByteArray(path.toFile)
val readFromFile = ScalaKryoInstantiator.defaultPool.fromBytes(byteArray).asInstanceOf[Map[String, String]]
`

Expected behavior
I would expect to be able to write the encoded byte array to file, read it back, and deserialize properly
