Description

With an AVDL of:

  @namespace("com.foo")
  record SomethingWithDec {
    decimal(8,2) dec;
  }

and the Scala/Java code of:

object Foo extends App {
  import com.foo.SomethingWithDec
  val x =  SomethingWithDec.newBuilder().setDec(new java.math.BigDecimal("1234"))
  val y = SomethingWithDec.newBuilder(x).build()
}

I get the exception:

Exception in thread "main" java.lang.ClassCastException: java.math.BigDecimal cannot be cast to java.nio.ByteBuffer
	at org.apache.avro.generic.GenericData.deepCopyRaw(GenericData.java:1089)
	at org.apache.avro.generic.GenericData.deepCopy(GenericData.java:1065)
	at com.foo.SomethingWithDec$Builder.<init>(SomethingWithDec.java:167)
	at com.foo.SomethingWithDec$Builder.<init>(SomethingWithDec.java:150)
	at com.foo.SomethingWithDec.newBuilder(SomethingWithDec.java:135)

I have attached the generated Java class for SomethingWithDec.

This seems related to AVRO-1895, but I believe that was meant to have been fixed in 1.8.2.
