-----------------------------------
Description:
When creating a dataset using the [Java Bean
Encoder|https://spark.apache.org/docs/3.2.0/api/java/org/apache/spark/sql/Encoders.html#bean-java.lang.Class-]
with a bean that contains a field which is a {{java.math.BigInteger}} the
dataset will fail to serialize correctly. When trying to serialize the dataset,
Spark throws the following error:
{code:java}
Exception in thread "main" org.apache.spark.sql.AnalysisException: Cannot up
cast `bigInteger` from struct<> to decimal(38,18).
{code}
Reproduction steps:
Using the Java Dataset API:
# Create a Bean with a {{java.math.BigInteger}} field
# Pass said Bean into the Java SparkSession {{createDataset}} function
