FULL PRODUCT VERSION :
java version "1.5.0_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_04-b05)
Java HotSpot(TM) Client VM (build 1.5.0_04-b05, mixed mode, sharing)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]

EXTRA RELEVANT SYSTEM CONFIGURATION :
German Windows (contains a space in the temp-directory where File.createTempFile() creates the file)

A DESCRIPTION OF THE PROBLEM :
System.load(String filename) fails if the filename contains a space character.
This is mostly the case if you create a file with File.createTempFile on a German Windows to copy a native library from a jar-file into it.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Try to load a library that's absolut path contains a space character
String path = "an absolut path with space chars"
System.load(path)

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
library should be loaded
ACTUAL -
I receive the following exception:

Exception in thread "main" java.lang.UnsatisfiedLinkError: C:\Documents and Settings\breuniga\Local Settings\Temp\SerialPort13860tmp: Can't find dependent libraries
...

ERROR MESSAGES/STACK TRACES THAT OCCUR :
see above

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
  To load a native library from a jar-file I use the following code:

InputStream inputStream =
   getClass().getClassLoader().getResourceAsStream(path);
File tmpLibraryFile = File.createTempFile(name, "tmp");
FileOutputStream outputStream = new FileOutputStream(tmpLibraryFile);
CopyUtils.copy(inputStream, outputStream);
outputStream.close();
System.load(tmpLibraryFile.getAbsolutePath()); <-- fails on German Windows


If I use a tmpLibraryFile without a space character in the path everything works fine.

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

CUSTOMER SUBMITTED WORKAROUND :
Create the tmpLibraryFile with File.createTempFile(name, "tmp", new File("path_without_space_chars").
But this is not a good solution, because I have to use a specific directory where the user must have write permissions and this path is platformdependent.
