          Well, The first thing I noticed in your Java Stack trace is that you are using an older version of the Java 1.6 JRE.  I recommend you upgrade at least to Java 1.6.0_45.  This could also just be an issue with the Java Cache.  It is always best to clear the Java Cache as the first trouble-shooting step.
