      Description

        As discussed in JDK-8202353, readdir_r is problematic and is being deprecated by various platforms. This is causing build failures on Linux when using recent versions of glibc. The replacement is readdir; the thread-safety issues with readdir are not a problem for most uses, including those in the JDK.

        The uses of readdir_r in java.base/unix/native should be changed to use readdir instead.
