I have a solution... Everyone should just use JDK 1.5. ;-) PS Sanjay, you can find out what version a given class was compiled if you look at the unsigned short integers starting at byte offset 4, right after 0xCAFEBABE in every class file. See this Javaworld article for more details, page 2: http://www.javaworld.com/javaqa/2003-05/02-qa-0523-version.html
