Problem with argument containing spaces
---------------------------------------

                 Key: EXEC-54
                 URL: https://issues.apache.org/jira/browse/EXEC-54
             Project: Commons Exec
          Issue Type: Bug
    Affects Versions: 1.1
         Environment: Mac OsX 10.6.6, JVM 1.6.0
            Reporter: Jeremias Rößler


I am new to Commons Exec, so this could also be an error in usage, but... 

When I use the {{CommandLine}} class to add a argument that contains spaces, some quotes are added and are then part of the argument that is given.

For example: When I call {{java "what version"}} I get {{java.lang.NoClassDefFoundError: what version}}, and when I call {{java "\"what version\""}} (which contains escaped quotes, that are part of the command line argument itself), I get {{java.lang.NoClassDefFoundError: "what version"}}.

So the following test fails, because as you can see in the last line, Apache Exec is producing the latter version where it should have produced the first version:

{code:java}
	@Test
	public void testArgumentQuoting() throws Exception {
		String argument = "what version";
		DefaultExecutor executor = new DefaultExecutor();
		DefaultExecuteResultHandler resultHandler = new DefaultExecuteResultHandler();
		ByteArrayOutputStream out = new ByteArrayOutputStream();
		PumpStreamHandler streamHandler = new PumpStreamHandler(out, out);
		executor.setStreamHandler(streamHandler);
		CommandLine cmdLine = new CommandLine("java");
		cmdLine.addArgument(argument);
		executor.execute(cmdLine, resultHandler);
		resultHandler.waitFor();
		String resultPattern = "Exception in thread \"main\" java\\.lang\\.NoClassDefFoundError: ([\\w \"]+)";
		Pattern pattern = Pattern.compile(resultPattern);
		Matcher matcher = pattern.matcher(out.toString());
		Assert.assertTrue(matcher.find());
		// Note: Result should be <what version> and NOT <"what version">!
		Assert.assertEquals(argument, matcher.group(1));
	}
{code} 

Note that the same test passes if the space is removed from the argument. Please also note, that I am not trying to start an external Java process, but this is merely an example that I assume will work on every developers machine.
