我们在WebSphere Application / WebSphere Commerce系统上安装了NewRelic java代理，在NewRelic日志中我们看到了这一点：

似乎有一些关于如何更新基于Eclipse的IDE环境以在其他情况下克服此错误的文档，但没有任何特定于NewRelic的文档。有没有人在此之前看到这个可以提供有关如何解决问题的建议？

New Relics Java代理的下一个版本应该可以在不进行任何配置更改的情况下运行。对于2.21.X及更早版本，请在support.newrelic.com上提交支持请求

我经历了同样的事情。正如您可能从Robban WebSphere所喜欢的文章中收集到的那样，SSLConnectionFactory中有一些限制，因此退出修复只需编辑 newrelic.yml 并配置：
# The agent communicates with New Relic via https by
# default. If you want to communicate with newrelic via http,
# then turn off SSL by setting this value to false.
# This work is done asynchronously to the threads that process your
# application code, so response times will not be directly affected
# by this change.
# Default is true.
ssl: false

New Relic的Java Agent 3.0.0或更高版本应完全解决此问题，无需任何自定义配置，当然不会关闭SSL！ Release notes.
