Hi Brian , looks like the function struct dirent64 *readdir64 (DIR64 *DirectoryPointer);
returns dirent64* ( according to https://www.ibm.com/support/knowledgecenter/no/ssw_aix_72/com.ibm.aix.basetrf1/opendir.htm ) and some of the files below still have dirent* on AIX ( at some places it is redefined ). For example : http://cr.openjdk.java.net/~bpb/8207744/webrev.02/src/java.base/unix/native/libjava/ProcessHandleImpl_unix.c.frames.html 508 jint unix_getChildren(JNIEnv *env, jlong jpid, jlongArray jarray, 509 jlongArray jparentArray, jlongArray jstimesArray) { 510 DIR* dir; 511 struct dirent* ptr; Not sure if this is really an issue in "real life" ....

I will take a look at what you observed. The whole process is a bit protracted since I cannot build and test but your assistance is appreciated. Thanks, Brian On Aug 2, 2018, at 5:24 AM, Baesken, Matthias <matthias.baes...@sap.com<mailto:matthias.baes...@sap.com>> wrote: builds + tests ( with your change included) last night on AIX were good . However while looking into the coding a bit more, I noticed the following : IBM states for AIX : https://www.ibm.com/support/knowledgecenter/no/ssw_aix_72/com.ibm.aix.basetrf1/opendir.htm Note An open directory by opendir64subroutine must always be closed with theclosedir64 subroutine to ensure that the next attempt to open that directory is successful. In addition, it must be operated using the 64-bit interfaces (readdir64, telldir64, seekdir64,rewinddir64, and closedir64) to obtain the correct directory information. However this is currently not the case everywhere : for example I see in http://cr.openjdk.java.net/~bpb/8207744/webrev.01/src/java.base/share/native/libjli/wildcard.c.frames.html a readdir (without 64). Same for http://cr.openjdk.java.net/~bpb/8207744/webrev.01/raw_files/new/src/java.base/unix/native/libjava/ProcessHandleImpl_unix.c
