Table annotation shouldn't be mandatory

[NicolaIsotta]

Right now, for CRUD operations, database table name is evaluated in this method:

SansOrm/src/main/java/com/zaxxer/sansorm/internal/Introspected.java

Lines 165 to 176 in ab22721

	/**
	* Get the table name specified by the {@link Table} annotation.
	*/
	private void extractClassTableName() {
	final Table tableAnnotation = clazz.getAnnotation(Table.class);
	if (tableAnnotation != null) {
	final String tableName = tableAnnotation.name();
	this.tableName = tableName.isEmpty()
	? clazz.getSimpleName() // as per documentation, empty name in Table "defaults to the entity name"
	: tableName;
	}
	}

If the class does not have the @Table annotation, tableName is null and this could lead to various type of confusing exception from the jdbc drivers, such as: com.microsoft.sqlserver.jdbc.SQLServerException: Incorrect syntax near the keyword 'null'.

Is the a reason why this method does not default to clazz.getSimpleName() when there is no @Table annotation?
