NoSuchFileException thrown by FileTreeWalker

[Andrew Scully]

Hi,

The below exception was thrown on a CentOS 7.1 system running Oracle
JDK 8u51 64-bit during a walk of a file directory:

 java.nio.file.NoSuchFileException:

The directory in question was probably being modified at the time, so
it's entirely possible that the file in question was deleted mid-walk.

The JavaDoc for the method
(https://docs.oracle.com/javase/8/docs/api/java/nio/file/Files.html#walkFileTree-java.nio.file.Path-java.nio.file.FileVisitor-)
states that an IOException is only thrown "if an I/O error is thrown
by a visitor method", but in this case it appears at least that the
exception is being thrown by the walker implementation itself.

The visitor in use is a java.nio.file.SimpleFileVisitor that overrides
the #visitFile() and #preVisitDirectory() methods only.

Any thoughts on how best to proceed (including a more appropriate
mailing list if this isn't the right one!) would be greatly
appreciated.

Kind Regards,
Andrew Scully.
