Song Guo Qiang updated DERBY-3363:
----------------------------------

    Attachment: DerbyBackupTest.zip

This test case helps to reveal the problems when Derby does not assign proper security domain to generated classes.

This folder contains a Eclipse project so you can open it and run the test case in the current folder.

> 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)
