   @jamesnetherton I rasie a PR on upstream camel to do some refactor on 
`JpaComponent` and it could be helpful for the graal substition. I think we can 
only add some substitions like
   
   ```java
   @TargetClass(JpaEndpoint.class)
   final class JpaEndpointSubstitution {
       @Alias
       private TransactionStrategy transactionStrategy;
   
       @Substitute
       protected EntityManagerFactory createEntityManagerFactory() {
           throw new UnsupportedOperationException("createEntityManagerFactory 
is not supported");
       }
   
       @Substitute
       public TransactionStrategy getTransactionStrategy() {
           return transactionStrategy;
       }
   }
   
   @TargetClass(JpaComponent.class)
   final class JpaComponentSubstitution {
       @Substitute
       private void createTransactionStrategy() {
       }
   }
   
   @TargetClass(DefaultTransactionStrategy.class)
   @Delete
   final class DefaultTransactionStrategySubstitution {
   }
   
   ```
