A DESCRIPTION OF THE PROBLEM :
when executing a command with "Runtime.getRuntime().exec" like this following command:
F:\\asp\\OFserver\\gs\\gs8.71\\bin\\gswin32c.exe @F:\\asp\\OFserver\\gs\\pdfwriter.rsp -sOutputFile="F:\\asp\\OFserver\\pdmw_pdf\\302234... - TUBO.pdf" "F:\\asp\\OFserver\\docs\\Administrador\\302234... - TUBO.pdf" -f

exec function remove one space from the name of pdf file


THE PROBLEM WAS REPRODUCIBLE WITH -Xint FLAG: Did not try

THE PROBLEM WAS REPRODUCIBLE WITH -server FLAG: Did not try

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
import java.io.IOException;

public class Test {
public static final void main(String[] args) {
try {
Process p = Runtime
.getRuntime()
.exec("F:\\asp\\OFserver\\gs\\gs8.71\\bin\\gswin32c.exe @F:\\asp\\OFserver\\gs\\pdfwriter.rsp -sOutputFile=\"F:\\asp\\OFserver\\docs\\Administrador\\302234... - TUBO.pdf\" \"F:\\asp\\OFserver\\pdmw_pdf\\302234... - TUBO.pdf\" -f");
} catch (IOException e) {
e.printStackTrace();
}
}
}

javac Test.java
java Test


EXPECTED VERSUS ACTUAL BEHAVIOR :
ghostscript generates a wrong file name pdf with blank contents
ERROR MESSAGES/STACK TRACES THAT OCCUR :
nothing

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
  To work arround this trouble I create a function that getShortName:
/**
     * returns the short filename (8.3) for a file in Windows
     *
     * @param longFileName
     * @return a string with the short filename, or null if an error occurred or the
     * file does not exist.
     */
    public String getShortName(String longFileName) {
String ShortName = "";
String FileName = "";
String strPath = "";

for(int x=longFileName.length()-1; x>0; x--) {
if(longFileName.charAt(x) == '\\') {
strPath = longFileName.substring(0, x+1);
break;
}
}

if(longFileName.indexOf(' ') > 0)
FileName += '\"';
FileName += longFileName;
if(longFileName.indexOf(' ') > 0)
FileName += '\"';
try {

File f = new File(longFileName);
if(f.exists())
System.out.println("Arquivo existe!");

String[] cmd = {"cmd", "/c", "dir", "/x", FileName};
Runtime r = Runtime.getRuntime();
Process p = r.exec( cmd );

InputStreamReader isr = new InputStreamReader(p.getInputStream());
BufferedReader br = new BufferedReader(isr);
String line = null;

boolean finished = false; // Set to true when p is finished

while( !finished) {
try {
while ((line = br.readLine()) != null)
ShortName += line;
// Ask the process for its exitValue. If the process
// is not finished, an IllegalThreadStateException
// is thrown. If it is finished, we fall through and
// the variable finished is set to true.
p.exitValue();
finished = true;
int i = ShortName.indexOf('~');
int j=i+1;
if(i < 0)
return longFileName;

for(;i>0 && ShortName.charAt(i) != ' '; i--);
for(;j<ShortName.length() && ShortName.charAt(j) != ' '; j++);
if(ShortName.charAt(i) == ' ')
i++;
//if(ShortName.charAt(j) == ' ')
// j--;
ShortName = ShortName.substring(i, j);
} catch (IllegalThreadStateException e) {
// Sleep a little to save on CPU cycles
Thread.currentThread().sleep(500);
}
}
} catch (Exception e) {
System.err.println( e);
}
return strPath + ShortName;
    }

and treated the spaces in the output file
