Description
JavaDB (or Derby) 10.5.1.1 can keep a database in-memory without disk access, which is convenient for test suites creating and destroying small databases. However this version is not yet deployed on Maven repository for the raisons exposed there:
https://issues.apache.org/jira/browse/DERBY-4267
This issue is for remembering us to upgrate to JavaDB 10.5.1.1 when we can. In-Memory databases are presented there:

The tests to update are MetadataWriterTest and IdentifierGeneratorTest in the geotk-metadata-sql module. But we should also consider testing the creation of the EPSG database from the scripts.
