Newbie Question "Cannot find user-level thread for LWP 26685: generic error"

[Jose Silva <joesilvas at gmail dot com>]

Hi, I'm a newbie using gdb and I don't understand what is happening, I
get something like this "Cannot find user-level thread for LWP 26685:
generic error". I am trying to debug some JNI code and I'm doing the
following:

gdb /usr/java/j2sdk1.4.2_03/bin/java

Cannot find user-level thread for LWP 26689: generic error

Can you help anybody help me out?
