Adding an explicit exit at the end of the code samples solves this problem. The former code was producing an error like below when run with mvn. ``` [WARNING] thread Thread[ForkJoinPool.commonPool-worker-3,5,com.hazelcast.cloud.ClientWithSsl] was interrupted but is still alive after waiting at least 15000msecs [WARNING] thread Thread[ForkJoinPool.commonPool-worker-3,5,com.hazelcast.cloud.ClientWithSsl] will linger despite being asked to die via interruption [WARNING] NOTE: 1 thread(s) did not finish despite being asked to via interruption. This is not a problem with exec:java, it is a problem with the running code. Although not serious, it should be remedied. ``` --- src/main/java/com/hazelcast/cloud/Client.java | 2 ++ src/main/java/com/hazelcast/cloud/ClientWithSsl.java | 2 ++ 2 files changed, 4 insertions(+) diff --git a/src/main/java/com/hazelcast/cloud/Client.java b/src/main/java/com/hazelcast/cloud/Client.java index faeacc1..92c54eb 100644 --- a/src/main/java/com/hazelcast/cloud/Client.java +++ b/src/main/java/com/hazelcast/cloud/Client.java @@ -41,6 +41,8 @@ public static void main(String[] args) { //nonStopMapExample(client);
