Java版本得LAC加载自定义词库之后多次调用，返回的分词结果存在问题？

1、JAVA版本加载自定词库，如果多次调用，返回的分词结果是混乱的。第二次分词结果会出现第一次分词里面的内容。现在的解决办法就是加载自定义文件，然后调用run，如果想再次调用，只能再次加载一次自定文件。

Start by reproducing the Java LAC behavior described: load a custom dictionary, call run multiple times, and compare the returned segmentation results. Trace the Java implementation involved in custom-dictionary loading and repeated run calls; done means each call returns only its own result without content from an earlier call, while preserving custom dictionary behavior.
