I tried to reproduce the issue in another machine again and I was able to. In addition I was able to run it as well successfully, the difference between the two runs is that in the successful one I got this warning message: ``` WARNING: Unmapping is not supported, because Lucene cannot read 'jdk.unsupported' module [please add 'jdk.unsupported' to modular application either by command line or its module descriptor] ``` So you need to make sure you can run MMAP (maybe you need to add `--add-modules jdk.unsupported`) which points to the readInts implementation in `ByteBufferIndexInput`. Just a quick check by removing the implementation shows that the error disappears. I had a look into the method and I could not spot anything strange. More over, I replaced the line: ``` guard.getInts(curIntBufferViews[position & 0x03].position(position >>> 2), dst, offset, length); ``` with: (Not reusing the int buffers) ``` IntBuffer intBuffer = curBuf.duplicate().order(ByteOrder.LITTLE_ENDIAN).position(position).asIntBuffer(); guard.getInts(intBuffer, dst, offset, length); ``` And the error disappear. ~~Not sure what is going on, maybe a jdk bug?~~ EDIT: I see you found it, we were not reseting the views when setting a new cur buffer. -- This is an automated message from the Apache Git Service.
