Joshua McKenzie updated CASSANDRA-8544:
---------------------------------------
Attachment: 8544_show_npe.txt
Some questions:
bq. It happens sometimes after restarts caused by undeletable files under
Windows.
How frequently is "sometimes"?
What files are undeletable?
How are you resolving / working around this? Does it work after another
attempt to restart?
Do you have steps to reproduce this?
Attaching a patch that should print out some more details on the NPE if you can
reproduce it consistently.
