#21 Java crash when no webcam is available

[Fabrizio Bellini]

If I want to use the jmyron.jar, when there isn't webcam connected, happens a crash of java VM
I see the crash happens executing the method native_update().

It is possible to insert a method which advise that there isn't webcam connected or there is an error during the native_start().
This to protect the code against the crash.

This is the log when it is execute the method native_update()
