Alternative VM for OpenJDK 11 with enhanced class redefinition

 The Dynamic Code Evolution Virtual Machine (DCE VM) is a modification of
 the Java HotSpot VM that allows unlimited redefinition of loaded classes
 at runtime. The current hotswapping mechanism of the HotSpot VM allows
 only changing method bodies. This enhanced VM allows adding and removing
 fields and methods as well as changes to the super types of a class.
 .
 This alternative VM is enabled by adding the -dcevm option when invoking
 the java command.
