Fix ParallelWorldClassLoader#close to close all JarFiles even on failure

[iamsanjaymalakar]

Problem

ParallelWorldClassLoader#close() attempts to close all tracked JarFile instances. it closes them sequentially without handling exceptions. If one close() throws, the method exits immediately and the remaining JarFiles are never closed.

Fix

• Wrap each jar.close() in a try/catch.
• Continue closing the remaining streams even after a failure.
• After attempting all closes, throw the first exception (and attach later ones as suppressed, if present).
