...at the time of that failure "single" was not a valid lockType for the
StandardDirectoryFactory - but it was a valid lockType for other facotries.
the error message doesn't make that clear though -- so if you had "single" in
your config for a while, and then later change the factory you'll suddenly get
a weird error even though you know that "single" use to be valid.
---
ideally the error message should be something like "lockType "foo" not
supported when using directoryFactory "bar", valid lock types for this
directory: yaz, zot, zing"
> better error message when lockType doesn't work with directoryFactory

> SOLR-6519 improved the logic about which lockTypes could be configured with
> which directoryFactory implementations, but the result is a somewhat
> confusing error message.
