In JarAnalyzer.java:38:
private static final Pattern CLASS_FILTER = Pattern.compile("[A-Za-z0-9]*\\\\.class$");The character class [A-Za-z0-9] excludes _ (underscore), which is a legal character in Java class names. Any class like My_Helper.class, some_test.class, or UPPER_CASE.class inside the JAR is silently ignored and never analyzed. This causes incomplete class discovery, potentially missing packages, imports, and leading to incorrect JDK revision detection.
Fix: Add _ to the character class: [A-Za-z0-9_]*\\\\.class$
