Which  version of AIX is this failing on? I notice that for AIX 5.3, the usage of LIBPATH is being migrated to LD_LIBRARY_PATH with LIBPATH as a fallback.

Jtreg when setting up the test with the "/native" on the @run line adds `test.nativepath` to `LIBPATH`.
What I'm puzzled by is the original case in which `test.nativepath` was appended to `LIBPATH` and passed to the child and yet the child returns the value of `LIBPATH` without `test.nativepath`.
It may not be material to fixing the errors, but does make me curious about what's really going on.
