Review comment:
The intention is to provide default value `None` for the errorClass and
potential future added fields like sqlState. Especcially if new fields are
added, this interface can simply be extended to
```scala
protected def interceptParseException(parser: String => Any)(
sqlCommand: String, messages: String*)(
errorClass: Option[String] = None, newField: Option[String] = None):
```
and the caller doesn't need to change its signature. For example,
``` scala
private def intercept(sqlCommand: String, messages: String*): Unit =
interceptParseException(parsePlan)(sqlCommand, messages: _*)()
private def intercept(sqlCommand: String, errorClass: Option[String],
messages: String*): Unit =
interceptParseException(parsePlan)(sqlCommand, messages: _*)(errorClass)
```
will still compile.
