Spaces in path to JAR leads to exception "Location does not exist."

[scito]

Configuration.getSupportCodeLocation() line 205 of matconsolectl-4.4.2 does not support spaces in path to the code location. Spaces are taken from URL where spaces could be encoded as %20. However this String path is directly put into a Java File path where the space encoding is not handled properly.

//Convert from url to absolute path
String path = url.getFile(); // Path is URL encoded, ie it could contain %20 for spaces
...
File file = new File(path).getCanonicalFile(); // Expects a "normal path"

Proposition: Convert URL directly into a File:

File file = new File(url.toURI()).getCanonicalFile();
