JDK-8226245 readdir implementation

[Kate Fox]

Hello,

According to https://bugs.openjdk.java.net/browse/JDK-8226245 I think the usage of readdir_r has been switched over to use readdir instead?

I checked build 1.8.0_292-b10 and it still uses readdir_r.  (I looked at the source code and still see that as the implementation in UnixNativeDispatcher.c.

Is there a jdk8 version with this fix?

Thank you for your help,

Kate
