Problem
PackageScanner#getClasses()opens JarFile instances when scanning "jar"/"wsjar" resources but never closes them. If scanning or class loading throws, the opened JARs are also left unclosed.Fix
Close all opened JarFiles in a finally block. The cleanup continues closing remaining JARs even if one close fails, and rethrows the first IOException with subsequent failures added as suppressed exceptions.
