However, at this point, the JVM has executed quite a lot of Java code and there are many threads in the JVM that would require a proper shutdown. See [comments by @kimbarrett](https://bugs.openjdk.org/browse/JDK-8360164?focusedId=14792754&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14792754) for a detailed analysis.
