Root Cause Analysis

The vulnerability stems from missing initialization of the deserialization filter in HardenedObjectInputStream's constructor. The fix commit (7018a36) adds the missing initObjectFilter() call, and the accompanying test case demonstrates that without this fix, malicious HashSet structures could be deserialized (triggering HashDoS). The direct correlation between the missing filter initialization and the security test case confirms this as the root cause.
