Perhaps that filter/Filter.java path has subtree mergeinfo that is not
correct somehow. Maybe it's missing the last character in some of the
paths (like in the mail you referenced). I suggest you check the
mergeinfo on that Filter.java path directly.

Also, the bug that caused the missing last character in mergeinfo has
been fixed in 1.8.4. See this post from a user who has confirmed, and
seen his corrupt mergeinfo being fixed by a subsequent merge:
