我有前端和后端服务器。
前端运行 Play！2.5 和 akka 2.4.11 后端运行 akka 2.4.11
两者都运行 kamon 0.6.3，并具有以下依赖项：
"io.kamon" %% "kamon-akka" % Version.kamon,
"io.kamon" %% "kamon-log-reporter" % Version.kamon,
"io.kamon" %% "kamon-system-metrics" % Version.kamon,
"io.kamon" %% "kamon-core" % Version.kamon,
"io.kamon" %% "kamon-akka-remote" % Version.kamon,
"io.kamon" %% "kamon-statsd" % Version.kamon,
"io.kamon" % "kamon-play-25_2.11" % Version.kamon
在 build.sbt 我有以下内容：
aspectjSettings
javaOptions <++= AspectjKeys.weaverOptions in Aspectj
fork in run := true
我从 aspectj weaver 开始后端：
-javaagent:./aspectjweaver/aspectjweaver-1.8.9.jar
在 plugins.sbt 我添加了以下插件：
addSbtPlugin("io.kamon" % "aspectj-play-runner" % "0.1.3")
但是，当我启动后端和前端时，当我的前端节点加入后端集群时，我立即在后端收到以下异常。
