Subject Lucene.net 4.3 failing test case - Merge Background Exception
Date Tue, 01 Oct 2013 15:38:40 GMT
All,

Here's an example of where merge hits a background exception in the 4.3
branch of lucene.net. I can't figure this one out.

https://gist.github.com/paulirwin/6780136

Here's the exception: background merge hit exception: _4(4.3.1):C1
_1(4.3.1):C1 _2(4.3.1):C1 _3(4.3.1):C1 _5(4.3.1):C1 _0(4.3.1):C1 into _6
[maxNumSegments=1]

I can see that the exception is an IndexOutOfRangeException happening in
Lucene.Net.Codecs.Compressing.LZ4.ReadInt, as it's trying to get a value
out of a byte buffer at an index that is way larger than the buffer length.
I can't yet determine how or why it's getting that very high value.

You need to build Core and Analyzers to use this code. I just threw it in a
console app.

Thanks!
Paul Irwin
