    Affects Versions: 4.2.0
            Reporter: Maxim Solodovnik
             Fix For: 4.2.0

**(medium)** `createPersistenceStructure`, `dropPersistenceStrucuture`, 
`validatePersistenceStruture` and `truncateData` each create a Broker via 
`super.newBrokerImpl(...)` that is only used for `getClassLoader()` and never 
closed - a broker (and its resources) leaked per call. Can the classloader be 
obtained without instantiating a broker?
