Files.isHidden() throws ArrayIndexOutOfBoundsException on Linux

[Christian Stein]

Hi,

Is the following worth creating an issue at bugs.openjdk.java.net for?

Running JShell 16-ea on Linux:

jshell> Files.isHidden(Path.of(""))
|  Exception java.lang.ArrayIndexOutOfBoundsException: Index 0 out of
bounds for length 0
|        at UnixFileSystemProvider.isHidden
(UnixFileSystemProvider.java:355)
|        at Files.isHidden (Files.java:1637)
|        at (#30:1)

Same Windows returns a value without throwing an exception:

jshell> Files.isHidden(Path.of(""))
$1 ==> false

Cheers,
Christian
