Java KeyClope-无法启动嵌入式服务器：WFLYEMB0022:无法调用'；启动'；关于嵌入式进程：参数'；抽象路径&x27；不能是空的

我通过容器注册表在Heroku PM dyno上有一个独立运行的KeyClope实例。最近，此应用程序因以下日志而崩溃。自5月25日以来，我一直没有更改代码，当时一切正常。heroku dyno没有接近任何极限。我的本地版本很好。因此，我认为一定发生了以下情况之一

• 基于独立设置的部署数据的某些损坏
• 基础映像中的更改-keydrope/11.0.2
• 容器注册表中的损坏图像正在覆盖内容

我尝试过的调试：

• 已验证db设置是否正确-它们正常
• 已验证数据库上的查询是否按预期工作-也可以
• 重新启动应用程序，部署应用程序，重建映像-所有错误消息都相同
• 使用新映像12.0.0重新部署应用程序-相同的错误消息
• 通过一个按钮部署了此映像的一个简单版本（）——这在第一次部署时起作用，并按预期连接到数据库。然而，当我重新发布和重新发布完全相同的代码时，同样的错误出现了

下一步我应该试试什么

日志：

---

我遇到了完全相同的问题，并能够通过设置一个全新的KeyClope Heroku应用程序来解决这个问题，在那里重新部署我的代码，然后重命名我的应用程序，以便旧应用程序的流量可以在何时到达新应用程序。如果需要的话，我可以提供详细的信息，但这导致了一个新的KeyClope服务器（dyno），它曾经扩展到性能-M，运行起来与以前完全相同（好吧，KeyClope配置存储在基础数据库中，因此如果您将原始数据库连接到新的dyno应用程序，那么您应该会很好）

在过去的一周左右，我遇到了完全相同的问题。实际上，我也在运行另一个版本的keydepeat，v10，最初尝试升级到v13来解决这个问题，但没有成功。我认为你是对的，有一些腐败正在发生，因为我的例子在第一次失败发生时也未被触及。我检查了Heroku变更日志，查看是否有任何会影响我的部署的内容，因为失败似乎发生在每日dyno重启之后，但我没有发现任何内容。）

---

我认为您是对的，这里存在某种损坏或潜在的bug，很可能是难以复制的，可能是使用WildFly代码、JVM、Keyclope或与Heroku相关的东西。很难从日志中分辨出来，但看起来好像有什么东西试图错误地添加路径，或者路径是空的。
