In my investigation, this issue happened after JDK-8272600 was applied.
  [JDK-8272600](https://bugs.openjdk.java.net/browse/JDK-8272600) (test) Use native "sleep" in Basic.java

It added `/native` on `@run` tag.

- @run main/othervm/timeout=300 -Djava.security.manager=allow Basic
- @run main/othervm/timeout=300 -Djava.security.manager=allow -Djdk.lang.Process.launchMechanism=fork Basic
+ @run main/othervm/native/timeout=300 -Djava.security.manager=allow Basic
+ @run main/othervm/native/timeout=300 -Djava.security.manager=allow -Djdk.lang.Process.launchMechanism=fork Basic

For this change, `test.nativepath` setting added into `LIBPATH` environment variable on parent (main) process.

Older AIX might require parent's `LIBPATH` setting against child process on some of cases.
But it seems the current AIX does not require `LIBPATH` setting.
#7581 applied parent `LIBPATH` setting against child process.
Please choose the appropriate one.
