Hi Liam,

This is a problem with the OS X JVM. Please see:




In short, you need to set the property 
derby.storage.fileSyncTransactionLog=true when starting Derby on OS X. 
I have reported this issue to Apple, as have others.

Jean, could we please have the FAQ updated to reflect that this issue 
affects modifying an existing database on OS X as well as creating a 
new database?
