These options include - * options which select which style of vm is run (e.g. -client and - * -server) as well as options which select the data model to use. - * Additionally, for tools which invoke an underlying vm "-J-foo" - * options are turned into "-foo" options to the vm. This option - * filtering is handled in a number of places in the launcher, some of - * it in machine-dependent code. In this file, the function - * CheckJVMType removes vm style options and TranslateApplicationArgs - * removes "-J" prefixes. On unix platforms, the - * CreateExecutionEnvironment function from the unix java_md.c file - * processes and removes -d<n> options. However, in case - * CreateExecutionEnvironment does not need to exec because - * LD_LIBRARY_PATH is set acceptably and the data model does not need - * to be changed, ParseArguments will screen out the redundant -d<n> - * options and prevent them from being passed to the vm; this is done - * by using the machine-dependent call - * RemovableMachineDependentOption. - */ - -#include <stdio.h> -#include <stdlib.h> -#include <string.h> - -#include <jni.h> -#include <jvm.h> -#include "java.h" -#include "manifest_info.h" -#include "version_comp.h" -#include "wildcard.h" -#include "splashscreen.h" - -#ifndef FULL_VERSION -#define FULL_VERSION JDK_MAJOR_VERSION "."
