benwtrent opened a new pull request, #13369:
URL: https://github.com/apache/lucene/pull/13369

   The issue outlines the problem. When we have point value dimensions, segment 
core readers assume that there will be point files. 
   
   However, when allowing soft deletes and a document fails indexing failed 
before a point field could be written, this assumption fails. Consequently, the 
NRT fails to open. 
   
   I tried many different ways of fixing this issue.
   
    - Delaying on setting the field info until document writes are successful. 
But this causes weirdness with global field numbers and other assumptions and 
checks later in the document life-cycle
    - Reverting the field info if a all the docs for a field fail to index, but 
this causes other weirdness and edge cases that seemed too sharp to mess with.
   
   So, I settled on always flushing a point file if the field info says there 
are point fields, even if there aren't any docs in the buffer.
   
   I am happy to consider other options.
