What is the proper way to close H2?

Question

This is related to this post.
I think I am having problem with H2 meaning that it does not close properly.
I suspect this since I see myDB.lock.db

By looking at the DbStarter.contextDestroyed()'s code (thanks to Allan5's answer), here is the code that will work:

connection.createStatement().execute("SHUTDOWN");

So Aaron Digulla's answer was correct (even if not fully "copy/pastable").

Moreover, if you have started an H2 TCP server using server = Server.createTcpServer("-tcpAllowOthers"), you can stop it simply using server.stop().
