示例1: getCookieInstructionLocation

import org.apache.bcel.generic.ALOAD; //导入方法依赖的package包/类
/**
 * This method is used to track calls made on a specific object. For instance, this could be used to track if "setHttpOnly(true)"
 * was executed on a specific cookie object.
 *
 * This allows the detector to find interchanged calls like this
 *
 * Cookie cookie1 = new Cookie("f", "foo");     <- This cookie is unsafe
 * Cookie cookie2 = new Cookie("b", "bar");     <- This cookie is safe
 * cookie1.setHttpOnly(false);
 * cookie2.setHttpOnly(true);
 *
 * @param cpg ConstantPoolGen
 * @param startLocation The Location of the cookie initialization call.
 * @param objectStackLocation The index of the cookie on the stack.
 * @param invokeInstruction The instruction we want to detect.s
 * @return The location of the invoke instruction provided for the cookie at a specific index on the stack.
