JVM源码阅读

在阅读JVM源码的时候，有很多地方都看不懂，但是又查询不到相关资料。如

CASE(_monitorenter): {
  // lockee 就是锁对象
  oop lockee = STACK_OBJECT(-1);
  // derefing's lockee ought to provoke implicit null check
  CHECK_NULL(lockee);
  // code 1：找到一个空闲的Lock Record
  BasicObjectLock* limit = istate->monitor_base();
.......

如代码中的指针istate就不是很明白是什么意思，导致代码阅读很艰难。大佬有什么学习心得或者学习方法吗，是否可以传授一些经验呢

十分感谢
