> JDBC4 driver-autoloading, introduced by DERBY-930, increases the exposure to
> non-deterministic startup behavior described in DERBY-1428. With the
> introduction of driver-autloading, DERBY-1428 can be triggered if OtherApp is
> any application which uses a JDBC driver. That is, OtherApp could use a Derby
> client driver, the DB2JCC driver, the Oracle client driver, etc.. The extra
> exposure arises because, with driver auto-loading, all JDBC drivers are
> registered and the Derby engine boots the first time some application asks
> for a Connection.
> The issues are summarized in an email thread
> http://mail-archives.apache.org/mod_mbox/db-derby-dev/200606.mbox/browser and
> bug report DERBY-1399.
> Workarounds are similar to those for DERBY-1428:
> 1) Determine the derby properties BEFORE the VM starts.
> 2) If that is not possible, then force the self-configuring embedded
> application to run first.
