更新 NewRelic 版本在运行时抛出 AbstractMethodError答案

【问题标题】：Updating NewRelic version throwing AbstractMethodError at runtime更新 NewRelic 版本在运行时抛出 AbstractMethodError
【发布时间】：2023-03-07 13:46:01
【问题描述】：

我正在一个项目中将 newrelic 版本从 2.x.x 更新为 5.x.x。我按照 newrelic 文档中提到的步骤进行操作（我更新了 pom 文件中的依赖版本，更新了代理 jar 文件和配置文件）。

但是现在在运行项目时传递了所需的 javaagent：

java -server -javaagent:/Users/amit.upadhyay/abcproject/abcproject-app/newrelic-stage/newrelic.jar -jar abcproject-app/target/abcproject-app-*.*.*-SNAPSHOT.jar /Users/amit.upadhyay/Downloads/abcproject.yml

我得到 java.lang.AbstractMethodError。以下是错误日志：

由于我在运行时遇到AbstractMethodError，即在某处我正在使用旧接口，该接口在新版本的 newrelic java agent 5.x.x 中更新。

错误日志表明我的项目中使用的xerces 版本与更新的newrelic javaagent 中存在冲突。在谷歌搜索中，我发现这两个 SO 链接 first 和 second 有类似的问题。根据给出的答案，我添加了

        <dependency>
            <groupId>xerces</groupId>
            <artifactId>xercesImpl</artifactId>
            <version>2.11.0</version>
        </dependency>

        <dependency>
            <groupId>xml-apis</groupId>
            <artifactId>xml-apis</artifactId>
            <version>1.4.01</version>
        </dependency>

到我的 pom 文件，这个 AbstractMethodError 错误消失了。

但在再次运行时，我开始收到此异常：com.newrelic.agent.config.ConfigurationException

此异常的日志是：

Mar 16, 2020 02:37:18 +0530 [9598 1] com.newrelic INFO: Configuration file not found. The agent will attempt to read required values from environment variables.

现在，我不明白为什么会抛出ConfigurationException（或者为什么找不到配置文件）。与旧版本的 newrelic 代理（2.x.x 或 3.x.x）一起使用时，相同的 java 命令（代理 jar 和配置文件的路径完全相同）运行完美。

我想了解这里出了什么问题/遗漏了什么？

【问题讨论】：

标签： java maven newrelic xerces

【解决方案1】：

我能够在我的项目中更新到最新的 newrelic 版本。似乎他们已经在其 Java 代理中更新了 xerces 版本，其中版本大于 5.0.0。随着更新xerces 版本的修复，我需要将newrelic 配置文件显式传递为系统属性来解析ConfigurationException。

总体总结： - 将这些库更新为

        <dependency>
            <groupId>xerces</groupId>
            <artifactId>xercesImpl</artifactId>
            <version>2.11.0</version>
        </dependency>

        <dependency>
            <groupId>xml-apis</groupId>
            <artifactId>xml-apis</artifactId>
            <version>1.4.01</version>
        </dependency>

并将 newrelic 配置文件作为系统属性传递：

-Dnewrelic.config.file=./${NEW_RELIC_DIR_NAME}/newrelic.yml
