jcmd, windows x64: cannot see other processes?

[Markus Gronlund]

Hi Thomas,

 

Are you running in two separate Terminal Server Sessions? 

 

You need to be in the same WindowsStation https://msdn.microsoft.com/en-us/library/windows/desktop/ms687096(v=vs.85).aspx

Hi all,

 

I try to attach a jcmd to a running process on windows x64, but jcmd only lists its own process.

 

Both jcmd and process are built from jdk-hs.

 

Then I tried attaching jdk-hs tip jcmd to an older VM (jdk 9), did not work either.

 

Then - and here it gets weird - I tried attaching a jdk9 jcmd to a jdk9 Vm, and still nothing... am I making a thinking error here? Do I need special options on Windows? On Unix this never gave me any trouble.

 

Both processes run under the same user, from two console windows. I tried both within and without cygwin too, does not make any difference.

 

Thanks, Thomas
