我试图坚持使用Geography(POINT, 4326)数据类型的实体。由于Hibernate Spatial无论如何都不支持地理，我使用byte[]来映射它（然后使用JTS进行转换）。
第一次保存实体时效果很好，但我会在更新其他属性后再次加载并保存，并在Invalid endian flag value encountered上获取save()。
实体中的定义：
@Column(columnDefinition="geography(POINT, 4326)")
private byte[] location;
这里的代码在save()上失败了：
task.setProcessed(true);
TaskRepository.save(task);
这是例外：

我正在使用Hibernate Core（4.3.1.Final），hibernate-spatial-4.3-SNAPSHOT（我需要SNAPSHOT用于我遇到的其他一些问题），使用PostgreSQL JDBC驱动程序9.3-1101-jdbc41和PostgreSQL 9.3数据库w / PostGIS 2.1.3在Windows 7 64位上。
P.S。我已经查看了其他有关此问题的stackoverflow问题，但它们与映射到Geometry而不是byte[]有关。
