jmap崩溃,“无法获取类数据”

有一个Java核心转储; 运行jmap

/usr/java/jdk1.8.0_25/bin/jmap -dump:format=b,file=dump.hprof /usr/bin/java core.31497 

给出以下例外:

 Attaching to core core.31497 from executable /usr/bin/java, please wait... ... JVM version is 25.25-b02 ... Exception in thread "main" java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:483) at sun.tools.jmap.JMap.runTool(JMap.java:201) at sun.tools.jmap.JMap.main(JMap.java:130) Caused by: sun.jvm.hotspot.utilities.AssertionFailure: can not get class data for sun/nio/ch/ThreadPool$$Lambda$10x00000007c0214428 at sun.jvm.hotspot.utilities.Assert.that(Assert.java:32) at sun.jvm.hotspot.utilities.HeapHprofBinWriter.writeInstance(HeapHprofBinWriter.java:803) ... at sun.jvm.hotspot.tools.Tool.start(Tool.java:223) at sun.jvm.hotspot.tools.Tool.execute(Tool.java:118) at sun.jvm.hotspot.tools.HeapDumper.main(HeapDumper.java:83) 

有什么想法吗?

正如@sethwm提到的这是一个已知的错误。

它已从Java 8 Update 60开始修复。
