---------------------------------------

GitHub user nicolas-dutertry opened a pull request:

    https://github.com/apache/aries/pull/95

    [ARIES-1887] ComponentTxData in transaction-blueprint was not thread safe

    I have replaced HashMap with ConcurrentHashMap.
    Because ConcurrentHashMap does not support null values, I have used Optional<TransactionalAnnotationAttributes> as value type.

> The class ComponentTxData in org.apache.aries.transaction.blueprint uses a HashMap
> {code:java}
> private Map<Method, TransactionalAnnotationAttributes> txMap = new HashMap<Method, TransactionalAnnotationAttributes>();{code}
> This is very dangerous because txMap can be modified and accessed after initialization.
> It should be replaced with a ConcurrentHashMap.
