Java New File Method can't write to an NFS v4 file system on LINUX while executed from an AIX client

Issue

An application hosted on an AIX 6.1 server uses the "new file" method to create files on an nfs mount point mounted from  LINUX 5.5 as NFS v4.  Java exception is thrown while executing the code as unprivileged user. In fact, on the AIX system (client), the newly created file is seen with permission 000.

The file is truely created if the code is executed with root user privileges.

Below code will reproduce this bug.

File file = new File(path);
file.createNewFile();
if ((delete != null) && (delete.equals("yes"))) {
   file.delete();
