## Bug #3 `DefaultDownloadManager.java` lines 57, 79, 148 The `cache` field (line 57) is a plain `HashMap` accessed in the non-synchronized `download()` method: `cache.get(url)` at line 79 and `cache.put(url, downloaded)` at line 148. If multiple threads call `download()` concurrently, `HashMap` can corrupt its internal structure, causing infinite loops, lost entries, or `NullPointerException`. Replace with `ConcurrentHashMap` or synchronize access. -- This is an automated message from the Apache Git Service.
