          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Reteoo
    Affects Versions: 4.0.4

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.
