LIST 70 ============================================================================ magic This field must have the value 0xCAFEBABE. minor_version, major_version These fields contain the version number of the Java compiler that produced this class file. An implementation of the virtual machine will normally support some range of minor version numbers 0-n of a particular major version number. If the minor version number is incremented the new code won't run on the old virtual machines, but it is possible to make a new virtual machine which can run versions up to n+1. A change of the major version number indicates a major incompatible change, one that requires a different virtual machine that may not support the old major version in any way. The current major version number is 45; the current minor version number is 3. ============================================================================
