public final class ConnectionKeeper
- extends Object
This class is used to keep connections open to the database while JIRA is running. It is used with HSQLDB as HSQLDB,
when running in-process, will shutdown as soon as no connections are open to it. When a new connection is opened to
the HSQLDB it will start up again. However, this causes problems as more than one HSQLDB instance may be created at
the same time and the two instances interfere wuth each other, possibly causing data loss.
As advised in the HSQLDB documentation, if HSQLDB is used in-process, a connection to it should be open at all times,
to prevent the database from shutting down. One connections seems not to be good enough, though (probably due to a
HSQLDB bug). Two connections does the trick.
Schedule the connection keeper.
