Closed as a dup of JDK-8169086

I have tried to reproduce this failure locally on Linux x64 by running the test in a loop, but it didn't fail.

At first glance, it is not clear if it is bug in test or DTLS implementation. We've already had issues with similar exceptions, see JDK-8161086 and JDK-8161086 which have been actually fixed in JDK-8167680. So, this needs more investigation.

The test has been recently added for JDK-8167680. I am attaching a jtr file with full logs.
