Johann,

While this approach might work, the preferred way to achieve this kind 
of batch reading is to implement RepositoryService.getItemInfos(). Here 
you can return arbitrary ItemInfos in a single batch. The jcr2spi module 
will then put these into the hirarchy without additional calls to the 
spi layer. See also https://issues.apache.org/jira/browse/JCR-1797
