Understanding -nativepath and how it is applied

I have a test that uses native code.
I specify "@run main/othervm/native" for the main test class
I invoke jtreg with -nativepath
My test exec's a second VM that needs to load the native library. This
is done using ProcessTools.executeTestJvm.
When I run the test locally it works fine and if I print out
java.library.path it shows that the "nativepath" value has been set in
But when I run the test via our testing system it fails because the
native library cannot be found! The jtr file shows -Dtest.nativepath
being set as expected, but the exec'd VM doesn't have its value in
I can obviously fix this by explicitly adding -Djava.library.path=... as
an explicit arg to the exec'd VM, but I want to understand how this
works in the local case but not otherwise.
I'm also wondering whether this is something that should be
automatically handled at the ProcessTools level?
