【问题描述】：
当我使用存储过程运行以下简单路由时，会导致异常：“java.sql.SQLException: Non supported SQL92 token at position”
具有嵌入式 Derby 数据源的相同路由按预期工作。
问题
有什么想法吗？我的“实现”有问题还是底层 jar 文件有问题？
堆栈：
- 骆驼2.23.2
- ojdbc7.jar
- Spring XML
路线：

存储过程： 我知道该过程在 oracle db 中不起作用，但在相关类/方法识别到该过程不工作/甚至不存在之前“很长时间”抛出异常。
CREATE PROCEDURE INOUTDEMO(IN1 INTEGER, INOUT IN2 INTEGER, OUT OUT1 INTEGER)
PARAMETER STYLE JAVA
LANGUAGE JAVA
EXTERNAL NAME
'org.apache.camel.component.sql.stored.TestStoredProcedure.inoutdemo';
