   ### Fix <bug description or the bug issue number or bug issue link>
   - [ ] Add a unit test to verify that the fix works.

      Just add ;DB_CLOSE_DELAY=-1 to the database URL for H2StorageConfig
      
      See the [In-Memory Databases](http://h2database.com/html/features.html#in_memory_databases)
section of the Features page. To quote:
      > By default, closing the last connection to a database closes the database. For
an in-memory database, this means the content is lost. To keep the database open, add ;DB_CLOSE_DELAY=-1
to the database URL. To keep the content of an in-memory database as long as the virtual machine
is alive, use jdbc:h2:mem:test;DB_CLOSE_DELAY=-1.
   - [x] If this pull request closes/resolves/fixes an existing issue, replace the issue number.
Closes #5541 
   - [x] Update the [`CHANGES` log](https://github.com/apache/skywalking/blob/master/CHANGES.md).
