> In MapBackedClassLoader three methods have access to the "store" property - addClass, fastFindClass and getResourceAsStream.
> fastFindClass is used in synchronized loadClass method, but addClass modifies the store without any synchronization. 
> MapBackedClassLoader is connected to one rulebase which can be shared between different working memory, so it is possible that multiple threads access the store concurently.
