RFR(xxxs): 8203014: jcmd should output command list if no command is given

[Volker Simonis]

Hi Thomas,

I think the request sounds reasonable and the change looks good.

@David: why should this require a CSR request? I don’t see that the
behavior for bad command line flags is specified somewhere. So we’re
changing an undocumented behavior into o more meaningful undocumented
behavior.

Regards,
Volker
