ModelMapper.processJarPackage nested JAR files read error

[lmxsoft]

Describe the bug
When processing a JAR package, the code fails to correctly handle nested JAR files. Specifically, when the packageURL is a nested JAR URL, the jarFileName is incorrectly decoded, leading to a failure in creating the JarFile object.

Here is the problematic code:

  private static void processJarPackage(URL packageURL, String packageName, String pkg, ArrayList<String> names) throws IOException {
    String jarFileName = URLDecoder.decode(packageURL.getFile(), "UTF-8");
    JarFile jf = null;
    // jar: client in repository; nested: client in a fat jar
    if (jarFileName.startsWith("jar:") || jarFileName.startsWith("nested:")) {
      jf = ((JarURLConnection) packageURL.openConnection()).getJarFile();
    }
    // file: client is a file in target (unit test)
    if (jarFileName.startsWith("file:") ) {
      jarFileName = jarFileName.substring(5, jarFileName.indexOf("!"));
      jf = new JarFile(jarFileName);
    }
    if (jf == null) {
      logger.error("Loading classes from jar with error packageURL: {}", jarFileName);
      return;
    }
    logger.info("Loading classes from jar {}", jarFileName);
    Enumeration<JarEntry> jarEntries = jf.entries();
    while (jarEntries.hasMoreElements()) {
      processJarEntry(jarEntries.nextElement(), packageName, pkg, names);
    }
    jf.close();
  }

For example, given the following URL:

Url packageURL = new Url("jar:file:/app/app.jar!/BOOT-INF/lib/java-client.jar!/io.kubenrnetes.client.openapi.models.V1Job");
String jarFileName = URLDecoder.decode(packageURL.getFile(), "UTF-8");

The jarFileName will be decoded as:
”file:/app/app.jar!/BOOT-INF/lib/java-client.jar!/io.kubenrnetes.openapi.models.V1Job”
This causes the JarFile to fail to initialize.
Proposed Fix:

Change:

String jarFileName = URLDecoder.decode(packageURL.getFile(), "UTF-8");
to:

String jarFileName = URLDecoder.decode(packageURL.toString(), "UTF-8");
Client Version

Client Version
e.g. 23.0.0
