Hi Sameer,

I don't think this is a problem in itself. The messages above look like 
JVM debug messages to me.

Derby compiles SQL queries into Java byte code, and this code is written 
to classes with names like above.
Note that you should be using prepared statements where possible, 
otherwise Derby may be generating more Java classes than necessary 
(hurting performance).


Hope this helps,
