JHAT 无法分析内存转储
我有一个内存转储文件，JHAT 给出以下消息，但我无法分析任何内容（因为没有显示数据。
Resolving 0 objects...
WARNING: hprof file does not include java.lang.Class!
WARNING: hprof file does not include java.lang.String!
WARNING: hprof file does not include java.lang.ClassLoader!
这是否意味着 hprof 文件不完整或损坏？
我正在使用-XX:+HeapDumpOnOutOfMemoryError" 我的 tomcat 中的选项。
I have a Memory Dump file and JHAT gives the following message and I cannot analyze anything (as no data is displayed.
Resolving 0 objects...
WARNING: hprof file does not include java.lang.Class!
WARNING: hprof file does not include java.lang.String!
WARNING: hprof file does not include java.lang.ClassLoader!
Does this mean the hprof file is incomplete or corrupt?
I am using-XX:+HeapDumpOnOutOfMemoryError"
option in my tomcat.

我刚刚在自己的堆转储中遇到了同样的问题。
NullPointerException看起来这种情况发生在没有足够的磁盘空间时转储堆的时间，因此文件确实不完整/损坏。

I just came across this same issue with my own heap dump.
NullPointerExceptionIt looks like this happens when there is not enough disk space at the time that the heap is dumped, so the file is indeed incomplete/corrupt.

我今天也有同样的问题。为了澄清这一点，我使用的选项
heap=sites与内存转储不同。我还从jhat和jvisualvm收到相同的消息。jhat可能不支持读取heap=sites模式创建的HPROF文件。I have the same problem today. To clarify, I am using the option
heap=siteswhich is different than a memory dump. I also get the same messages fromjhatandjvisualvm. It is possible thatjhatdoes not support readingHPROFfiles created byheap=sitesmode.
