For others who may have "unable to load main class ... " error.
363 version is compiled under class file 59 and JDK 15 is right version for it.
I had both JRE and JDK installed and caused this problem.
Now I am at another problem. I believe this too is version issue.
Error message;
L1DatabaseFactory.getConnection WARNING: L1DatabaseFactory: getConnection() failed, trying again java.sql.SQLException: Unable to open a test connection to the given database. JDBC url = jdbc:mysql://localhost:3306/l1jdb?useUnicode=True&characterEncoding=UTF-8, username = root. Terminating connection pool (set lazyInit to true if you expect to start your database after your app). Original Exception: ------

server is running and tested connection on workbench. They are fine.
Anybody faced this issue before?
