run shutdown() and start() on same EmbeddedStorageManager instance?

[tomschulze]

Hi,

Is it somehow possible to do this:

storageManager.shutdown();
storageManager.start();

In my minimal working example the testCanRestart test fails with the exception

one.microstream.storage.exceptions.StorageExceptionConsistency: No roots found for existing data.

Thank you!

Doing a restart of an existing EmbeddedStorageManager instance is currently not possible.

To restart a storage without a VM-Restart you can create a new EmbeddedStorageManager instance with an identical configuration after shutting down the first one.

Please note that you must not reuse any existing instances of foundations and configured components to create the EmbeddedStorageManager, you should re-create those components too.

ok thanks for the quick reply! that helps a lot.
