[jira] [Commented] (SOLR-8742) HdfsDirectoryTest fails reliably after changes in LUCENE-6932
[

Mark Miller commented on SOLR-8742:
---
Or I was mistakenly in an older, similarly named project.
I can't see where the mistake is in Solr code. We seek to the last byte in the
file and then we try to read a byte and expect EOF, but instead get a
nullpointer because currentBuffer is never set in this case.
