I have met this problem when I start up my wowza1.5.3 server.

java.lang.reflect.InvocationTargetException

i think this is a java problem rather than a wowza problem and it isnt wowza that is failing to start but your java, that will then prevent wowza from starting.

I would suggest that you update your java and try starting wowza after that

Maybe an update has switch the default java command back to the incorrect version of Java. See if this post helps:
