how to get default vm parameter value or the value of a running process?

[Bernd Eckenfels]

Hello,

for a running process you can use jinfo to print the flags set on the
comamnd line. Those flags and the one set by ergonomics will be
printed with "jcmd PID VM.flags" and a full list of all flags in effect
is printed by "jcmd PID VM.flags -all". (java8)

Gruss
Bernd
