Houston Putman created SOLR-17645:
-------------------------------------
Summary: Handle executor thread failures more gracefully
Key: SOLR-17645
URL: https://issues.apache.org/jira/browse/SOLR-17645
Project: Solr
Issue Type: Bug
Affects Versions: 9.8
Reporter: Houston Putman
As of SOLR-17448, we use ExecutorService.execute() much more throughout the
codebase. This is a good thing since before we weren't doing anything with the
Future objects that ExecutorService.submit() would return.
One drawback however, is that in our tests, we use randomizedTesting (the
library) to listen for uncaught exceptions in threads. I believe the change to
ExecutorService.execute() led to this, because there is no Future to return
that an exception was thrown.
Usually we do well in catching exceptions in our threads, but certainly not
always. We should audit this, to improve error handling in our code as well as
limit test failures.
