/**
* Locates the {@link JarUtil#getJarFileUri(Uri) Jar file Uri} of a given resource relative to a

* <pre>

*
* Example #1
*
* <pre>
* classFromJavaJar = com.lighting.Test (in: file:/storage/TestLighting.jar)
* cutOffInclSubDir = lights/
* relResPath = LightAssets.jar
* Result : file:/storage/lights/LightAssets.jar

* Example #2
*
* <pre>
* classFromJavaJar = com.lighting.Test (in: file:/storage/lights/TestLighting.jar)
* cutOffInclSubDir = lights/
* relResPath = LightAssets.jar
* Result : file:/storage/lights/LightAssets.jar
* </pre>
*
* TODO: Enhance documentation!
*
* @param classFromJavaJar Used to get the root Uri for the class's Jar Uri.
* @param cutOffInclSubDir The <i>cut off</i> included sub-directory prepending the relative
* resource path. If the root Uri includes cutOffInclSubDir, it is no more added to the
* result.
* @param relResPath The relative resource path. (Uri encoded)
* @return The resulting resource Uri, which is not tested.
* @throws IllegalArgumentException
* @throws IOException
* @throws URISyntaxException
