我们正在使用使用 sun.nio 包的第三方应用程序。我们经常遇到以下错误，

java.lang.NullPointerException
    at sun.nio.ch.Util.free(Util.java:199)
    at sun.nio.ch.Util.offerFirstTemporaryDirectBuffer(Util.java:176)
    at sun.nio.ch.IOUtil.write(IOUtil.java:50)
    at sun.nio.ch.SocketChannelImpl.write(SocketChannelImpl.java:334)

直到服务器重新启动后才会停止。总体内存消耗仍保持在 30%。

我尝试搜索 this 和 sun.nio 包，但找不到任何指向它的指针。我正在寻找以下

任何关于 sun.nio 包源代码的文章、文档
都会有很大的帮助。
如果你们对这种情况下“可能”发生的事情有任何暗示，请分享。

This does not stop until the servers are restarted. Overall memory consumption remains at 30%.

I tried searching for this and sun.nio package but could not get any pointers to it. What I am looking for followings
