Java tomcat 8.5 el api上的Spring迁移4.3到5错误

在tomcat 8.5上使用Spring启动初始值设定项将Spring 4.3升级到5时，我们开始遇到异常：

el api jar取自tomcat/lib，我们还将el api版本从2改为3，仍然引发异常

对于这种例外情况是否有已知的解决方案

可以忽略吗

我发现它不会被修复

EPEL el6于2020年11月30日变更为寿命终止（EOL）状态。EPEL6是 不再维护，这意味着它将不会收到任何进一步的 安全或错误修复更新。因此，我们正在关闭此错误

您偶然发现了错误：

META-INF/services/javax.el.ExpressionFactory

文件中的注释没有被跳过，因此出现了奇怪的错误

---

此问题已在Tomcat版本中修复。

您使用的是哪个版本的Tomcat？堆栈跟踪的行号似乎不匹配。

el-api.jar

来自哪里？@PiotrP.Karwasz tomcat版本8.5.50，el-api.jar来自tomcat库
