One of the hardest types of bugs to track down is a deadlock situation. They are very time dependant which makes them intermitten, specific to a particular computer and configuration and generally impossible to reproduce in a debugger. Fortunately, at least in Java, it’s fairly easy to spot most of the situations where a deadlock is possible:

Here is some great news for Nokia S60 users, apparently Nokia has been working on revamping the security framework on Java applications and the nagging permissions we continuously need to give in order for them to work, may soon be a thing of the past.
