> I did some quick debug. I guess the problem happens because Derby generates some classes
on the fly but forgets to assign proper security domains when loading the generated classes
(such as 'org.apache.derby.exe.ac3a7f0048x0117xc98bxe062x0000001202800'). When the generated
code tried to access some sun.* packages, the security check failed.
> Ideally, Derby code should call 
> ClassLoader.defineClass(String name, byte[] b, int off, int len, ProtectionDomain protectionDomain)

> instead of 
> ClassLoader.defineClass(String name, byte[] b, int off, int len)
