Description

The @Transactional interceptor currently fails with a NullPointerException if no EntityManager can be found for the requested qualifier.

java.lang.NullPointerException
	at org.apache.deltaspike.jpa.impl.transaction.ResourceLocalTransactionStrategy.getTransaction(ResourceLocalTransactionStrategy.java:296)
	at org.apache.deltaspike.jpa.impl.transaction.ResourceLocalTransactionStrategy.rollbackAllTransactions(ResourceLocalTransactionStrategy.java:262)
	at org.apache.deltaspike.jpa.impl.transaction.ResourceLocalTransactionStrategy.execute(ResourceLocalTransactionStrategy.java:141)
	at org.apache.deltaspike.jpa.impl.transaction.TransactionalInterceptor.executeInTransaction(TransactionalInterceptor.java:57)

Instead there should be an exception telling the user what exactly is wrong so that it is easier to fix such an issue.
