This a change to a bunch of serviceability tests (shell scripts that launch
the various j* tools (jps, jstatd, jstack etc)) that I'd like to push
through the TL JDK repo.
The changes were done by Carlos Lucasius but I'm acting as his "sponsor" for
getting these pushed.
Summary: for correct operation the tools and/or the VM they target must be
running with UsePerfData enabled. This VM option is enabled in Java SE by
default, but is disabled in Java SE Embedded by default. To allow the tests
to be used regardless of the UsePerfdata setting they are augmented to
explicitly turn it on.
There has been some prior internal debate around how "best" to deal with
this issue and the resulting changes, while somewhat repetitive, are the
simplest approach to take.
There is one test - jps/jps-Vvml_2.sh - that can not pass with such a fix
because it is actually trying to test the jps output when no arguments (VM
or application) are passed to the target VM. So for that test I've just
added a comment.
