Hey, Luigi. I posted a new patch to the bug you were working on, JIRA DERBY-2649. The patch allows you to build correctly in the Derby codeline. I also attached a jar file containing a NetBeans Java Web Start project that tries to use the JNLP storage engine, and a description of the failures I got.
Are you available to take a look at this? It would be great to try and move this forward. If you have any questions, please let us know. Thanks, David
