Description
https://mail.openjdk.java.net/pipermail/serviceability-dev/2019-February/027240.html
When I attached to VM which is after 8215622 change via jcmd in JDK 8 on Linux, jcmd hanged.
I checked the status of target VM and jcmd, LinuxAttachListener::read_request() on target VM was waiting for
subsequent argument.
JDK-8215622 increased number of arguments of Attach API [1].
Thus AttachListener will be waiting the command from client infinitely.
