Error message on the derby.log while booting the database using jdk1.5

[Manjula G Kutty]

Hi,
I'm getting the following error message on my derby.log while booting a 
database using jdk15

*"Class org.apache.derby.jdbc.Driver40 
java.lang.UnsupportedClassVersionError: Bad version number in .class 
file, module ignored."
*

I would like to know is this the same issue  as people discussed on the 
thread, with subject : Re: conflict between Derby API and JDBC 4.0?

Here is thre thread, but I don't know whether it has all the mails, this 
is my best try

If so I would like to what is the solution to fix the problem.


Thanks
