A bug in filesystem bootstrap (unix/ linux) prevents (original) (raw)

Hi folks.

Run the following with -Dfile.encoding=UTF-16:

public class TestBlah { public static void main(String []) throws Exception { TimeZone.getDefault(); } }

This on linux (and any unixish system I think) will result in:

java.lang.ExceptionInInitializerError at java.nio.file.FileSystems.getDefault(FileSystems.java:176) at sun.util.calendar.ZoneInfoFile$1.run(ZoneInfoFile.java:482) at sun.util.calendar.ZoneInfoFile$1.run(ZoneInfoFile.java:477) ...

There is an encoding-sensitive part calling getBytes on the initial path (and this screws it up):

// package-private
UnixFileSystem(UnixFileSystemProvider provider, String dir) {
    this.provider = provider;
    this.defaultDirectory = UnixPath.normalizeAndCheck(dir).getBytes();
    if (this.defaultDirectory[0] != '/') {
        throw new RuntimeException("default directory must be absolute");
    }

Filed a bug for this but don't have the ID yet.
