Rick Hillegas updated DERBY-1459:
---------------------------------
Attachment: bug1459_v02.diff
Attaching bug1459_v02.diff, which hopefully addresses Dan's concern. In this
version the public EmbeddedDriver has a rather than is an AutoloadeDriver.
> Early load of Derby driver with JDBC 4.0 autoloading can lead to derby
> properties not being processed or derby boot time actions consuming resources
> when a connection is made with another driver

> The addition of support for autoloading of Derby drivers, DERBY-930, caused
> two potentially serious regresions for applications.
> 1) Early load of driver can mean that derby system properties, such as
> derby.system.home may not be processed by the driver because they are set
> after the driver is loaded.
> 2) Early load of the driver can mean boot time operations, such as starting
> network server with derby.drda.startNetworkServer can happen even when Derby
> is never used if a connection is made to another database such as Oracle.
> The attached file autoloading_scenarios.html shows scenarios that show these
> regressions plus another case that will regress if boot time operations are
> moved to the first Derby embedded connection. I don't know what solution is
> available that would handle all three cases.
