Subject RE: class file has wrong version?
Date Wed, 01 Dec 2004 17:18:04 GMT

Hi,
If you compile a class with J2SE 5.0 (class file version 49.0), you
can't run it with JDK 1.4 (class file version 48.0), unless you
specifically told the compiler -target 1.4.  This is a mismatch between
your compile-time and run-time JVM versions.
