Subject Is create=true thread-safe?
Date Fri, 20 Mar 2020 05:24:39 GMT
Hi,

Is the create=true attribute
<https://db.apache.org/derby/docs/10.12/ref/rrefattrib26867.html>
thread-safe?

In particular, what would happen if 10 threads at the same time try to
obtain this connection:

    DriverManager.getConnection("jdbc:derby:mydb;create=true);

(when Derby is used as an embedded database)? Is this safe?

The docs say:

> If the database already exists, the attribute creates a connection to the
existing database, and an *SQLWarning* is issued.

But it is not clear if that implies `create=true` is thread safe.
