Linux and MacOS already had specific implementations. After the removal of the Solaris port, these two functions can be removed in favor of inline implementations of os_getParentPidAndTimings and os_getCmdlineAndUserInfo in src/java.base/aix/native/libjava/ProcessHandleImpl_aix.c.

Hi Christoph, I adjusted the COPYRIGHT info and removed unix_getChildren .
Regarding 'Solaris' mentioning in this file , I removed that one too but a grep shows there are plenty of  Solaris comments etc. in the codebase.
