请问 DirectMemoryMonitor类里面的 Field maxMemory = c.getDeclaredField(“DIRECT_MEMORY_LIMIT”) && Field reservedMemory = c.getDeclaredField(“DIRECT_MEMORY_COUNTER”) 的值是哪里获取的，为甚么一直为空？

had this same error (although I was using jdk 11). i was using zuul-core 2.1.4, updating to 2.1.8 fixed it.
I believe this commit was responsible for the fix.
I can’t repro this. Do you have steps?
