Wrong gson deserialization of list of integers #18397
Description
Compiler version
3.3.0
Minimized code
//> using dep com.google.code.gson:gson:2.10.1
//> using scala 3.3.0
import com.google.gson.Gson
import scala.jdk.CollectionConverters._
case class HasArray(
argIndices: java.util.List[Integer]
)
object Main {
def main(args: Array[String]): Unit = {
val gson = new Gson();
val arr =
gson.fromJson[HasArray]("{ \"argIndices\" : [1,2,3]}", classOf[HasArray])
println(arr.argIndices)
}
}Output
[1.0, 2.0, 3.0]the elements in the list are actually Doubles.
Expectation
[1, 2, 3]This worked ok in the previous Scala versions 2.13.x.
