Attempts to call into a java applet from Java Script fail silently. Setting

trace level to 3 does show indication that something occurred, however no
error or warning is presented. The output displayed in the console has no
clear relation to the blocking of Java Script, however this output only
occurs upon attempting to do so. These two lines are displayed with each
attempt to call into Java from JS:
 
    Created version ID: 1.7.0_45
    Created version ID: 1.7.0_25

What this means is currently unclear.
 
Here are two suggestions:
 
    1. A warning that Java Script was blocked should be presented in Trace
        level 0 in the Java Console.
 
    2. The warning should be clear and simple so an end-user can understand.

        For example, "Java Script calls from the browser have been blocked."
