The numbers are sourcecode-lines, yes. Try the following with jdb:
jou@db:~ jdb -Djava.compiler=NONE Tedit
initializing jdb...

main[1]: where
{.... list of stack ...}
main[1]: list
{sourceode}
main[1]: locals
{prints localVariableTable}
main[1]: print <id> (where id=variablename)
{info on object}
main[1]: dump <id> (where id=variablename)
{dump info on object}
Your problem is probably an instantiation-problem I'll guess. Trying
to add something which isn't allocated yet ?, like:
JPanel panel;
[code]
private void initComponents(){
getContentPane().add(panel);
}
