any ideas?

[Vlad Patryshev]

scala> def x: java.math.BigDecimal = null

x: java.math.BigDecimal

scala> Option(x)

res6: Option[java.math.BigDecimal] = None

scala> Option[BigDecimal](x)

java.lang.NullPointerException

Thanks,

     Hello,

  Not sure what is going on here, but note that BigDecimal is scala.math.BigDecimal, not java.mathBigDecimal.

     Best, Oliver

It should not make any difference, I think.

However, it does:

scala> def x: java.math.BigDecimal = null
x: java.math.BigDecimal

scala> x: scala.math.BigDecimal
java.lang.IllegalArgumentException: null value for BigDecimal
at scala.math.BigDecimal.<init>(BigDecimal.scala:406)
at scala.math.BigDecimal$.apply(BigDecimal.scala:334)

... 32 elided
