Java 错误数据库锁获取失败（带嵌入式hsqldb的Hibernate）

我尝试使用嵌入式hsqldb运行这个示例 （这是我第一次尝试使用嵌入式数据库）

这是我的hibernate配置文件：

<hibernate-configuration>
<session-factory>
<property name="hibernate.dialect">org.hibernate.dialect.HSQLDialect</property>
<property name="hibernate.connection.driver_class">org.hsqldb.jdbcDriver</property>
<property name="hibernate.connection.url">
jdbc:hsqldb:C:\Users\Desktop\testdb</property>
<property name="connection.pool_size">1</property>
<property name="show_sql">true</property>
<property name="hbm2ddl.auto">create</property>

org.hibernate.dialogue.hsql方言
org.hsqldb.jdbcDriver
jdbc:hsqldb:C:\Users\Desktop\testdb
1.
真的

这是日志文件：
