来自JVM崩溃的日志文件包含各种有用的调试信息，如加载的共享库和完整的环境。我可以强制JVM以编程方式生成其中的一个;通过执行崩溃它的代码或一些其他方式？

The log file from a JVM crash contains all sorts of useful information for debugging, such as shared libraries loaded and the complete environment. Can I force the JVM to generate one of these programmatically; either by executing code that crashes it or some other way? Or alternatively access the same information another way?

推荐答案

您可以尝试引发OutOfMemoryError并添加-XX：+ HeapDumpOnOutOfMemoryError jvm参数。这是新的1.6和McDowell建议的其他工具。 blogs.oracle/watt/ resource / jvm-options-list.html

You can try throwing an OutOfMemoryError and adding the -XX:+HeapDumpOnOutOfMemoryError jvm argument. This is new as of 1.6 as are the other tools suggested by McDowell. blogs.oracle/watt/resource/jvm-options-list.html
