Please explain to me.. if I have next statement:
private void doSomeThing()
{
try
{
Connection con = L2DatabaseFactory.getInstance().getConnection();
return;
}
catch {}
finally {L2DatabaseFactory.close(con);}
}

you shouldn't do that, it will most probably result in an unclosed connection.

You can try something like this:
Code: Select all
private void doSomeThing(){ try { Connection con = L2DatabaseFactory.getInstance().getConnection(); return; _log.warning("Return don't work here!") } catch {} finally { L2DatabaseFactory.close(con); _log.warning("DB connection was closed!") }}
Just need check the console XD

there's nothing to try, everybody knows that return is the end, it won't go past it.
