A JavaCallWrapper is constructed before each JavaCall and destroyed after the call. Its purpose is to allocate/deallocate a new handle block and to save/restore the last Java fp/sp. A pointer to the JavaCallWrapper is stored on the stack.
Note
this port is very minimal and is only designed to get frame traversal working. FIXME: we will have to add platform- specific stuff later and therefore a factory for these objects.
