    * Some platforms may have an upper limit on command line length.  For example,
    * the maximum command line length on Windows is 8191 characters, but the
    * length of the classpath may exceed this.  To work around this limitation,
    * use this method to create a small intermediate jar with a manifest that
    * contains the full classpath.  It returns the absolute path to the new jar,
    * which the caller may set as the classpath for a new process.
-   * 
+   *
    * Environment variable evaluation is not supported within a jar manifest, so
    * this method expands environment variables before inserting classpath entries
    * to the manifest.  The method parses environment variables according to
    * platform-specific syntax (%VAR% on Windows, or $VAR otherwise).  On Windows,
    * environment variables are case-insensitive.  For example, %VAR% and %var%
    * evaluate to the same value.
-   * 
+   *
    * Specifying the classpath in a jar manifest does not support wildcards, so
    * this method expands wildcards internally.  Any classpath entry that ends
    * with * is translated to all files at that path with extension .jar or .JAR.
-   * 
+   *
    * @param inputClassPath String input classpath to bundle into the jar manifest
    * @param pwd Path to working directory to save jar
    * @param targetDir path to where the jar execution will have its working dir
