You may also read in the release notes - "Changes to Runtime.exec" 
<http://www.oracle.com/technetwork/java/javase/7u21-relnotes-1932873.html#jruntime>:

> On Windows platform, the decoding of command strings specified to
> Runtime.exec(String), Runtime.exec(String,String[]) and
> Runtime.exec(String,String[],File) methods, has been improved to
> follow the specification more closely. This may cause problems for
> applications that are using one or more of these methods with
> commands that contain spaces in the program name, or are invoking
> these methods with commands that are not quoted correctly.
>
> For example, Runtime.getRuntime().exec("C:\\My Programs\\foo.exe
> bar") is an attempt to launch the program "C:\\My" with the
> arguments "Programs\\foo.exe" and "bar". This command is likely to
> fail with an exception to indicate "C:\My" cannot be found.
