class file format

Hi,

I'm writing a program that needs to process class files - thing is all I've got to go on is the online class file spec (http://java.sun.com/docs/books/vmspec/html/ClassFile.doc.html) which is for major/minor version 45.3. As you may or may not be aware - JDK 1.5.0 is compiling classes with class version 49.0.

What I really need to know is if the spec (in terms of reading a class file) has changed at all between the two above versions. If it has, where can I find an updated spec...or failing that find a list of changes to the current spec?

Thanks in advance for any help!

Alan

For a start, that link is old, the second edition of the VM Spec is here

http://java.sun.com/docs/books/vmspec/2nd-edition/html/VMSpecTOC.doc.html

Then follow the "Maintanence Information" at the top right hand corner of that page, and you'll get links to docs explaining the updates all the way to 1.5

regards,

Owen
