             Summary: Repeatable Read: Transactions are not isolated when read non-existing keys
                 Key: ISPN-3236
                 URL: https://issues.jboss.org/browse/ISPN-3236
             Project: Infinispan
          Issue Type: Bug
          Components: Transactions
    Affects Versions: 5.3.0.CR1
            Reporter: Pedro Ruivo
            Assignee: Pedro Ruivo
             Fix For: 5.3.0.Final


Repeatable read transaction is not isolated when they read a non-existing key.

tm.begin()
cache.get(k) //returns null
//in the meanwhile a transaction writes on k and commits
cache.get(k) //return the new value. IMO, this is not valid for 
REPEATABLE_READ isolation level!

//TODO add a test case for all the write operations (except put map because it does not read the old value)
 * put() //assert the return value
 * conditional put //if cache.get(k) returns null the putIfAbsent should never fail. Vice-version if cache.get(k) returns non-null
 * conditional replace //replace should never fail if used as old value the cache.get(k). And vice-versa
 * conditional remove //remove should never fail if used as old value the cache.get(k). And vice-versa
