Description

AvroSchema is taken from a compiled avsc file which contains a decimal field.

AvroSchema.Builder builder = AvroSchema.newBuilder();
BigDecimal bd = new BigDecimal(new BigInteger("155"), 3);
campaignBuilder.setDecimalField(bd);
AvroSchema source = builder.build();

//This line causes an exception
AvroSchema.Builder builder1 = AvroSchema.newBuilder(source);

Exception:

InvocationTargetException: java.math.BigDecimal cannot be cast to java.nio.ByteBuffer

The same failure happens with GenericData as well:

GenericRecord copy = GenericData.get().deepCopy(AvroSchema.getClassSchema(), source);
