> To at least provisionally fix [1] so as not to fail java/nio/file/FileStore/Basic.java on misconfigured systems, the patch [2] is proposed. This affects non-Windows systems only. As in the previous version, the FileStore enumeration test is skipped if the “df” command hangs a spawned process which is indicative of a network problem. In this version the FileStore enumeration test will also be skipped if any two lines of the “df” output are equal. In the previous version a RuntimeException would be thrown if two consecutive lines of the “df" output were equal and so the test would fail. This patch would remove that failure mode. Issue [3] is on file to perform further investigation of better handling of duplicate mount points at a later time.

This looks okay to me.
