I looked into this a little, and it appears that the bug that was fixed in the test framework didn't solve this. When adding a `Dispose(bool)` override to the `ICUCollationKeyFilter`, `Dispose(true)` is still being called followed by additional calls to `IncrementToken()`. This is occuring in `DocFieldProcessor` which [does a tight loop](https://github.com/apache/lucenenet/blob/081edeed35b190c1d535dcfdfeb91143f0ef818f/src/Lucene.Net/Index/DocFieldProcessor.cs#L280-L284) around some fields. It is possible that the consumer will dispose the `TokenFilter` in one loop and then another loop will retrieve the same instance of that `TokenFilter` by calling `Field.GetTokenStream(Analyzer)` and call `IncrementToken()` on it after it is disposed. At this point I haven't confirmed this is how it works in Java so it is still unclear if this is expected behavior or a bug. If the former, we should consider the possibility of making `TokenStream` "close" and do that separately than "dispose" (see #265). ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
