Description

Current implementation of Runtime kernel class in DRLVM is unable to handle non-English characters in file names properly. For example you cannot do Runtime.exec() if name of target executable contains Russian letters. Please see the test case below.

hello.c
—
#include <stdio.h>
int main() {
printf("%s\n", "Hello world!");
}

ExecWithLocalizedName.java
—
import java.io.*;

public class ExecWithLocalizedName {
public static void main(String argv[]) throws Exception {
Process proc = Runtime.getRuntime().exec(argv[0]);
InputStreamReader reader = new InputStreamReader(proc.getInputStream());
StringBuilder sb = new StringBuilder();
int c;

while ((c = reader.read()) != -1)

{ sb.append((char) c); }

reader.close();

System.out.println(sb.toString());
}
}

Compile everything (in MSVC environment):
cl hello.c -o здрасте.exe
javac ExecWithLocalizedName.java

If executed on J9 (or RI):
%J9_HOME%\bin\java ExecWithLocalizedName здрасте.exe
Hello world!

If executed on DRLVM:
%DRLVM_HOME%\bin\java ExecWithLocalizedName здрасте.exe
Uncaught exception in main:
java.io.IOException: The creation of the Process has just failed: "чфЁрёЄх.exe"
