Hi, The only known to us case of improper execution of JVM shutdown hook thread in case of graceful JVM termination - is a JVM bug https://bugs.openjdk.java.net/browse/JDK-8154017 when main thread is left in interrupted state. This was fixed in JDK 9 and backported to JDK 8, AFAIR to 8u162. Thus please
- make sure that JVM is gracefully terminated and not killed - check JVM version that you use - and state in which you leave main thread On Monday, August 6, 2018 at 1:25:04 PM UTC+2, Dhruv Vinayak wrote: > > Even i'm facing the same issue for a java process.
