Error # 750 : initialization error

Hi, I hope to find advice here, on how to solve this problem. I'm a beginner in Java. Really appreciate your help if you can offer any!
In using JBuilder 3.5 Foundation. Java 2 SDK v1.4.1_02 is used for compilation. An error is encountered in compiling a simple test program:
Error # 750 : initialization error; com.borland.compiler.symtab.LoadError : class file has wrong version 48.0
In some other source files, if this error is not there, a warning appears :
warning #910 : cannot check class java.lang.Exception; class file has wrong version 48.0; assuming package java.lang is stable; use of -nomakestable is recommended
**The Exception class appears because I've extended it in the new class defined. So, it can be other classes, as long as it's used in the source.
If I switched to using JDK v1.3.1, compilation completes normally.
I've checked to make sure that the Project Properties specify the correct path to the JDK definition when using v1.4.1.
But because my knowledge of the SDK is limited, I really need help on this. Can anybody advise ?
Thank you.

JBuilder 3.5 doesn't support 1.4 JVMs. Upgrade to JBuilder 2005 Foundation.

I agree. Here's the link:
