Miggo AIRoot Cause Analysis

The vulnerability stems from the use of e.printStackTrace() in notifyReadClosed, which bypasses proper logging mechanisms. The commit explicitly replaces this with a controlled logger (log.error()), confirming the vulnerability was in this method. While notifyWriteClosed was also patched, the CVE title and descriptions specifically reference notifyReadClosed as the primary vector. The direct connection between the vulnerability description, CWE-770 (resource allocation without throttling), and the patch confirms high confidence.
