在Java中，h2的IFEXISTS=TRUE是不应该的

Question

下面是引发的整个异常：

Exception in thread "main" org.h2.jdbc.JdbcSQLException: Unsupported connection setting " IFEXISTS" [90113-194]
at org.h2.message.DbException.getJdbcSQLException(DbException.java:345)
at org.h2.message.DbException.get(DbException.java:179)
at org.h2.message.DbException.get(DbException.java:155)
at org.h2.engine.ConnectionInfo.readSettingsFromURL(ConnectionInfo.java:269)
at org.h2.engine.ConnectionInfo.<init>(ConnectionInfo.java:77)
at org.h2.jdbc.JdbcConnection.<init>(JdbcConnection.java:100)
at org.h2.Driver.connect(Driver.java:69)
at java.sql.DriverManager.getConnection(Unknown Source)
at java.sql.DriverManager.getConnection(Unknown Source)
at Driver.<init>(Driver.java:18)
at App.<init>(App.java:6)
at App.main(App.java:13)

我完全遵循了the tutorial of H2。但结果并不理想。我只复制了代码IFEXISTS=TRUE，没有重新键入，所以不可能是打字错误。我做错什么了吗
