描述

Maybe InternalUtils.getRootCause()?

We should probably write a few tests.

The other question is whether our InternalUtils.getRootCause() needs to handle loops in the dependency chain. I think we should strongly consider keeping it simple as I doubt we have anything complicated enough to cause loops.

研究方向
First, examine the existing InternalUtils class in the bitcoinj source to understand current utility methods. The goal is to create a method `getRootCause(Throwable)` that replicates Guava's behavior without relying on Guava. Consider the issue's suggestion to keep it simple and not handle dependency loops. Write unit tests for the new method, covering normal cases and edge cases (e.g., null, chain of causes). Review the discussion in issue #4033 for any additional constraints or preferences.
