When an application received SIGTERM, if the data dog agent has not completely finished it's initialization, adding the shutdown hook results in an exception. Catching the exception and stopping the initialization process should avoid this. Example stack trace when this happens: ``` java.lang.IllegalStateException: Shutdown in progress at java.base/java.lang.ApplicationShutdownHooks.add(Unknown Source) at java.base/java.lang.Runtime.addShutdownHook(Unknown Source) at org.datadog.jmxfetch.App.run(App.java:154) at datadog.trace.agent.jmxfetch.JMXFetch$1.run(JMXFetch.java:131) at java.base/java.lang.Thread.run(Unknown Source) ```
