Hi,
In an earlier post [https://www.mobileread.com/forums/sho...eventlistener] I outlined that I ma using a nmea library in my kindle PW.

After fixing the build issues in the earlier post, I discovered that the kindle doesnt like:

private static final Logger LOGGER = Logger.getLogger(SentenceReader.class.getName());

and this:

private ConcurrentMap<String, List<SentenceListener>> listeners = new ConcurrentHashMap<String, List<SentenceListener>>();

For the logger fix I shamelessly used ixtabs logger class.
however for the ConcurrentHashMap I am not sure what to use instead and was hoping for some advice here.

The project builds fine but the kindlet gets stuck/ freezes at this method.

thanks
Nubble
