If you were using 2.X there is a setForceWriteLock() option which would have worked for you. 

As a workaround, you could do this:

1.  Configure your cache with R_R.
2.  Start your transaction.
3.  Whenever you need to READ a node, first WRITE a dummy value to it.  E.g., cache.put("/root/subroot/A", "dummy", null);  This will force a write lock on the node, and no other thread will be able to read it.
4.  Perform your READ.
5.  Commit your tx.
