I've been trying to get PreciousStones to work under one of the Bukkit compatible servers recommended for TekkitLite. I've been using MCPC-plus.

I'm running mcpc-plus-1.4.7-R1.1-SNAPSHOT-f524-164.jar available from the Jenkins builds here:

http://ci.md-5.net/job/MCPC-Plus/

I've added PreciousStones.jar to the plugins folder and I get the following error when the server starts.

I'm trying to debug why PreciousStones is unable to initialize the sqlite database while other plugins (e.g. Essentials) don't seem to be having a problem.

Let the server run longer and found that essentials was having issues as well. Seems they use a framework that retries connections for 30 attempts so it seemed like it initialized the databases correctly and loaded the plugin when in reality it was not.

I probably should close this issue and follow up with the MCPC devs.
