Description

Version 2.19.1 and the prior ones sent the event BYE and then the forked JVM exited.
This caused the stdin buffer could not be read completely.
The completion of JVM could not be marked in master process in Maven and therefore it was considered as a serious JVM error.
Version 2.19.2 implemented acknowledgement of JVM exit by sending BYE_ACK command from master to the fork.
