        Description

        FULL PRODUCT VERSION :
        $ java -version
        java version "9-ea"
        Java(TM) SE Runtime Environment (build 9-ea+159)
        Java HotSpot(TM) 64-Bit Server VM (build 9-ea+159, mixed mode)


        ADDITIONAL OS VERSION INFORMATION :
        Linux rhxxxx.microfocus.com 2.6.32-131.0.15.el6.x86_64 #1 SMP Tue May 10 15:42:40 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux


        EXTRA RELEVANT SYSTEM CONFIGURATION :
        No locale to be set.

        A DESCRIPTION OF THE PROBLEM :
        If there is a file present in the current directory whose name consists of ShiftJIS characters, and my locale is not set, 'javac HelloWorld.java' (obviously a trivial Java program) fails.

        REGRESSION. Last worked in version 8u121

        ADDITIONAL REGRESSION INFORMATION:
        java version "9-ea"
        Java(TM) SE Runtime Environment (build 9-ea+159)
        Java HotSpot(TM) 64-Bit Server VM (build 9-ea+159, mixed mode)


        STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
        First we must create a file with a Japanese ShiftJIS name.
        You need a terminal that supports Japanese ShiftJIS first. I do...

        $ LANG=ja_JP.SJIS xterm&

        ... which creates an xterm. I cannot read or write Japanese, so I then do 'ls notexist' to get an error in Japanese from 'ls', and cut and paste some Japanese characters from that error and use 'touch' to create the file...

        $ touch <pasted-Japanese-characters>

        There is now a file with a name consisting on ShiftJIS Japanese characters.
        In another terminal (or the Japanese one - it doesn't really matter) unset your language settings, and check your locale - it should now default to 'POSIX'

        $ unset LANG
        $ unset LC_ALL
        $ locale
        LANG=
        LC_CTYPE="POSIX"
        LC_NUMERIC="POSIX"
        LC_TIME="POSIX"
        LC_COLLATE="POSIX"
        LC_MONETARY="POSIX"
        LC_MESSAGES="POSIX"
        LC_PAPER="POSIX"
        LC_NAME="POSIX"
        LC_ADDRESS="POSIX"
        LC_TELEPHONE="POSIX"
        LC_MEASUREMENT="POSIX"
        LC_IDENTIFICATION="POSIX"
        LC_ALL=

        Next we'll be trying to compile 'HelloWorld.java' - here it is...

        public class HelloWorld {

            public static void main(String[] args) {
                System.out.println("Hello, World");
            }

        }

        ... now to compile it


        $ javac HelloWorld.java


        EXPECTED VERSUS ACTUAL BEHAVIOR :
        EXPECTED -
        HelloWorld.java compiles without any warning or error.
        ACTUAL -
        $ javac HelloWorld.java

        REPRODUCIBILITY :
        This bug can be reproduced always.

        ---------- BEGIN SOURCE ----------
        public class HelloWorld {

            public static void main(String[] args) {
                System.out.println("Hello, World");
            }

        }


        ---------- END SOURCE ----------

        CUSTOMER SUBMITTED WORKAROUND :
        If the locale is 'en_GB.UTF8' the compilation works.... and, yep ja_JP.utf8 also. C does not.

        $ export LANG=en_GB.UTF8
        $ javac HelloWorld.java
