我正在使用 RDF4J Virtuoso 适配器连接到在 VirtualBox CentOS 7.3 64 位中编译和安装的 Virtuoso 7.20.3216。
我尝试使用以下代码在 Virtuoso 中加载 Turtle 文件：
Repository r = new virtuoso.rdf4j.driver.VirtuosoRepository(url, login, password);
RepositoryConnection connection = r.openConnection();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
// Turtle data written inside baos
String graphUri = ... ;
connection.add(new ByteArrayInputStream(baos.toByteArray()), RDF.NAMESPACE, RDFFormat.TURTLE, SimpleValueFactory.getInstance().createIRI(graphUri));
Virtuoso 崩溃（停止）并显示以下日志：

当上传到指挥后台时，相同的 Turtle 字符串可以正常工作。这个文件很大，所以我不能在这里粘贴它。
我们已将问题缩小到字符编码问题。turtle 文件包含带有重音字符的文字，例如"Disque à gravure directe"@fr.
我们没有设置任何字符编码参数，无论是在 Virtuoso 配置端，还是在 JDBC 连接端。我们尝试添加charset=UTF-8JDBC 连接字符串，但没有成功。
似乎只有当数据库为空时才会出现问题。当数据库已经包含一些数据时，Virtuoso 不会崩溃。
任何想法
- 错误信息是什么意思？
- 问题的原因可能是什么？
- 如何解决或解决这个问题？
谢谢！
