Name: krC82822 Date: 10/01/2000 java version "1.3.0" Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0-C) Java HotSpot(TM) Client VM (build 1.3.0-C, mixed mode) It would be extremely useful to be able to obtain a full thread dump programmatically, e.g. by adding a method to java.lang.Runtime to return what otherwise can only be obtained by a Ctrl-C (SIGINT) in the console window. If the production version of our application hangs, we have no way of sending it an interrupt to obtain the thread dump. But we can add code to the application to get the dump on demand (say from a troubleshooting menu). For ease of parsing, it would be most convenient if: (a) each thread's stack backtrace was returned separately, either as a String or a custom class object; (b) each monitor in the monitor cache dump was returned separately, either as a String or custom class object. Looking at the JVM code, I can see that the String return values would be easier. Returning an array of Strings would be sufficient. Alternatively, perhaps an OutputStream could be supplied to the method and the thread dump written to the stream.
