Description

SOLR-8587 added segments file information and its size to core admin status API. However in case of stale commits, calling that API may result on FileNotFoundException or NoSuchFileException, if the segments file no longer exists due to a new commit. We should fix that by returning a proper value for the file's length in this case, maybe -1.
