启用 DEBUG 日志级别 WSO2 EI 6.1.1 时使用 PCML 连接器时 NativeWorkerPool 未捕获异常 java.lang.NoSuchMethodError

Question

我在Wso2 EI 6.1.1中使用AS400 PCML Connector调用AS400-DB2远程程序调用

问题： 如果在 log4j.properties(wso2ei-6.1.1\conf) 中为 rootlogger 启用 DEBUG 级别日志 ,PCML 调用不起作用并抛出错误：NativeWorkerPool 未捕获异常。

完整的堆栈跟踪：

示例 PCML 文件：

<pcml version="4.0">
 <program name="Validate" path="/QSYS.LIB/SVDGDG.LIB/PEB0012.PGM">
 <data name="inputNIC" type="char" length="15" usage="input" />
 <data name="inputIAC" type="char" length="4" usage="input" />
 <data name="outputStatusCode" type="char" length="1" usage="output" />
 </program>
</pcml>

在 log4j.properties 文件中启用 DEBUG 日志级别

log4j.rootLogger=DEBUG, CARBON_CONSOLE, CARBON_LOGFILE, CARBON_MEMORY, CARBON_SYS_LOG, ERROR_LOGFILE

PCML 连接器配置应用类似于此 link:https://docs.wso2.com/display/ESBCONNECTORS/Configuring+AS400+PCML+Connector+Operations

AS400 驱动实现 lib:jt400

注：

• 如果 DEBUG 级别日志更改为更高级别(info/error) PCML 调用 工作正常
• 我的实际要求是申请per-API DEBUG logs。由于以上 针对 per-API DEBUG logs 提出的问题，我尝试在 root 中全局启用 DEBUG 级别日志 记录器（根据 -API 日志禁用）。但问题仍然存在。
• 启用线路日志无法满足我的要求。

此错误是由于 jt400.jar 版本控制问题引起的。 可以使用最新版本的 jt400.jar（目前为 8.5 版）解决问题。
