I have the feeling this is caused by this lambda: https://github.com/apache/lucene/blob/f0483d3ce99e56ffbe433fc655c16e0bb5d760c2/lucene/core/src/java/org/apache/lucene/store/MemorySegmentIndexInput.java#L457 The problem with MemorySegments is: all code is backed by VarHandles and this could quickly cause wrong inlining decissions as all of this code relies on correct inlining. Looks like a VM bug. I'd suggest to reverr the above PR and check again. It looks like it does not works well perfectly with the current code in MMapDir. The code there is a bit tricky but relies stronly on correct inlining, especially regarding that specific lambda. Uwe -- This is an automated message from the Apache Git Service.
