Resource leak in JarAnalyzer constructor if entries.sort() throws

[elharo]

In JarAnalyzer.java, the constructor opens a JarFile and then sorts entries:

List<JarEntry> entries = Collections.list(jarFile.entries());
entries.sort(Comparator.comparing(ZipEntry::getName));  // NPE if entry has null name

If any JarEntry has a null name (possible in malformed ZIPs), Comparator.comparing throws NPE before the getManifest() try/catch block is reached. The JarFile handle is never closed, causing a resource leak.

Fix: Either validate entry names before sorting, or use a null-safe comparator:

entries.sort(Comparator.comparing(ZipEntry::getName, Comparator.nullsLast(Comparator.naturalOrder())));
