I was debugging the jre/bin/java of Harmony using gdb, I made a break point at main(); But when I run this program, gdb told me a new thread was created, then it swith to this thread and stopped at the first line of main(); I was wondering what does this thread came from? and what does it do before main()? The console is like this
(gdb) file java Reading symbols from /home/zhouxun/hdk/jdk/jre/bin/java...done. Using host libthread_db library "/lib/tls/i686/cmov/libthread_db.so.1".
