      It appears that somewhere in the jdk8 builds, the system encoding is leaking into the build process. This makes builds unpredictable.

      Hi Kelly,
       I have filed a bug whose internal review id is 2421470. It was filed with "Product/Category" being "JDK/JRE" and "Subcategory" being "Problems common to more than one tool". I am wondering since it only happens when building OpenJDK, is it eligible for a Java bug?
       In addition, do you have any idea on how to force java programs such as idlj to use ascii?

      Best regards,

      Hi Volker,
       Yes, I think so. The comment is pasted below.
      * org/omg/PortableServer/Current.java .
      * 由IDL-to-Java 编译器 (可移植), 版本 "3.2"生成

      It's in Chinese, and it says when translated to English that "Generated by IDL-to-Java compiler(portable) version 3.2 and the date. You can also view a "normal" English one under openjdk folder "corba\gensrc\" after performing a build.

      An relevant question is that in my env (export LANG=C), java output without any param always gives me Chinese help. Even though we may find out which env var or value jvm reads on startup, it could be impossible to change them. Any insight or idea on the mechanism is welcome.

      Best regards,

      This is just a wild guess, but perhaps idlj uses the value of some environment variables (or values derived from them - check System.getProperties()) which contain non ASCII characters? This could be something like PATH, HOSTNAME, USER. What exact characters are there in the comment and what kind of comment is it? How does this comment look on a "normal" system?

         Hi Kelly
           I investigated how local specific characters get into generated
         sources in corba module. Those classes are generated by following
         command idlj
         c:/openjdk/dep/jdk1.7.0_02/bin/idlj -J-XX:-PrintVMOptions
         -J-XX:+UnlockDiagnosticVMOptions -J-XX:-LogVMOutput -J-Xmx512m
         -J-Xms512m -J-XX:PermSize=32m -J-XX:MaxPermSize=160m -td
         -i "../../../../src/share/classes/org/omg/PortableServer" -i
         "../../../../src/share/classes/org/omg/PortableInterceptor" -corba
         3.0 -fall -pkgPrefix PortableServer org.omg

           I checked idlj help but there is no encoding specific option. My
         locale environment vars are listed below

         $ locale

           Could you give me any hint about how to force idlj to generate
         ascii chars only?

         Best regards,

             In the past, the "-encoding ascii" was important, all the
             reasons I can't completely list right now. But it is important
             that regardless of the locale, the bits created during the
             build should be the same for everyone.
             The definition of "same" might not be bit for bit, but by
             minimizing the potential differences we have a fighting
             chance of measuring "the same".

             But my question is, how are any locale specific characters
             getting into generated sources? That's what we need to find out.

             Removing "-encoding ascii" is probably not the right answer,
             and if it is, will require some debate.

                   I have an encoding problem when building openjdk 8 on my
                 Windows 7. My windows is Chinese environment but I
                 exported LANG=C in cygwin bash before building. The issue
                 is that in module corba and jdk, some java classes are
                 generated by program. They happen to contain Chinese
                 characters in comment. However, they are compiled with
                 explicit option "-encoding ascii" in makefile. This
                 results in unrecognizable chars complained by javac
                 (Error: encoding ascii unmappable chars) . I have a patch
                 that removes all unnecessary "-encoding ascii" but I am
                 not sure all its side effect. Shall I submit a bug?

                   Best regards,
