Command-line debugging with Java

Steps to debug Java apps in stone-age style:

1. Run your program with additional switches
   java -Xdebug -Xrunjdwp:transport=dt_shmem,server=y,address=MyAppName,suspend=n -cp . test
2. Run the command line debugger
   bin/jdb.exe -connect com.sun.jdi.SharedMemoryAttach:name=MyAppName
3. Tell the debugger where the sources are
   sourcepath C:/Cygwin/Home/Chui
4. Show list of threads, suspend the threads, display call stack, and step through code

$ bin/jdb.exe -connect com.sun.jdi.SharedMemoryAttach:name=MyAppName
Set uncaught java.lang.Throwable
Set deferred uncaught java.lang.Throwable
