I think manually coding the `file:// + path` URIs have cross-platform
issues.
For File URIs, I found it to be best to go with
```java
new File(string).toURI()
```
or in that specific case:
```java
localJarPath = new Path(new File(URLDecoder.decode(encodedJarPath,
Charset.defaultCharset().name())).toURI());
or
localJarPath = new Path(new URI("file", null,
URLDecoder.decode(encodedJarPath, Charset.defaultCharset().name()), null));
```
