In a MariaDB Server only used for an older JavaEE Application with Glassfish 5.1 and Eclipselink 2.8 suddenly appeard a database named
#mysql50#.java

I dont’t know how this could happen.

I was able to connect to this database in the MariaDB cli Interface by
connect ‘#mysql50#.java’
but commands like
show tables;
results in
ERROR: Can’t connect to the server

A
drop database ‘#mysql50#.java’;
or other ways to write it results in errors like
ERROR 1064 (42000); You hava an error in your SQL syntax; check the manual … to use near ”#mysql50#.java”

I would like to lists the tables but at least get rid of this database without changing any of the others.
Has anyone an idea?
