First, ClassCache is not meant to be serialized - I don't think this will  
change.

Now normally, you pass your top level scope to the ScriptableOutputStream  
constructor, hence it will be stubbed in the stream instead of being  
written out. ClassCache is set as an associated value of the top level  
scope, and top level scope being stubbed out, serialization should never  
reach the ClassCache through it either. So, either you:

a) have another path of references that reaches ClassCache (highly  
unlikely)
b) have an object that was serving as a top level scope previously, and  
you accessed Java objects (hence triggered ClassCache cretion) from code  
using it as a top level scope or (not too likely)
c) are not specifying your top level scope as the argument to  
ScriptableOutputStream constructor (likely).
