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 R=C3=B6=C3=9Fler


I am new to Commons Exec, so this could also be an error in usage, but...=
=20

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.NoClassD=
efFoundError: what version}}, and when I call {{java "\"what version\""}} (=
which contains escaped quotes, that are part of the command line argument i=
tself), I get {{java.lang.NoClassDefFoundError: "what version"}}.

So the following test fails, because as you can see in the last line, Apach=
e Exec is producing the latter version where it should have produced the fi=
rst version:

{code:java}
=09@Test
=09public void testArgumentQuoting() throws Exception {
=09=09String argument =3D "what version";
=09=09DefaultExecutor executor =3D new DefaultExecutor();
=09=09DefaultExecuteResultHandler resultHandler =3D new DefaultExecuteResul=
tHandler();
=09=09ByteArrayOutputStream out =3D new ByteArrayOutputStream();
=09=09PumpStreamHandler streamHandler =3D new PumpStreamHandler(out, out);
=09=09executor.setStreamHandler(streamHandler);
=09=09CommandLine cmdLine =3D new CommandLine("java");
=09=09cmdLine.addArgument(argument);
=09=09executor.execute(cmdLine, resultHandler);
=09=09resultHandler.waitFor();
=09=09String resultPattern =3D "Exception in thread \"main\" java\\.lang\\.=
NoClassDefFoundError: ([\\w \"]+)";
=09=09Pattern pattern =3D Pattern.compile(resultPattern);
=09=09Matcher matcher =3D pattern.matcher(out.toString());
=09=09Assert.assertTrue(matcher.find());
=09=09// Note: Result should be <what version> and NOT <"what version">!
=09=09Assert.assertEquals(argument, matcher.group(1));
=09}
{code}=20

Note that the same test passes if the space is removed from the argument. P=
lease also note, that I am not trying to start an external Java process, bu=
t this is merely an example that I assume will work on every developers mac=
hine.
