I don't have Internet connectivity from my computer but hit a serious problem with mixed jars trying to test 10.8 client with 10.5 server that I wanted to share as I will likely be disconnected until Monday.
If I have 10.8 derbyclient.jar followed by 10.5 derbyrun.jar in my classpath and try to make even an embedded connection, I get a NoSuchFieldError for JVMInfo.JAVA_SQL_TYPES_BOOLEAN. This field was required for 10.5 but removed sometime before 10.8. Thanks Katherine Sent from my iPhone
