Galder Zamarreño resolved ISPN-695.
-----------------------------------

    Fix Version/s:     (was: 4.2.0.BETA1)
                       (was: 4.2.0.Final)
       Resolution: Cannot Reproduce Bug


John, I'm closing this issue since we haven't been able to replicate the issue so far. As said on the forum, I don't think the NPE shown on the description is not really linked to ISPN-706. It'd be helpful to find out more about the circumstances and maybe some randomly failing test that we can use to replicate the issue here. In any case, I've sorted out a similar NPE as part of ISPN-699 and I have made the COT code more resilient and more informative in terms of what goes wrong when the reader externalizer returns null. This fix will be in next 4.2.x release to be out in the next few days.

> I have an application that wrote a bunch of cache data in remote server mode.  I then wanted to, starting with the same cache, compare the speed of the application in the embedded mode.  However, the data cannot be read from the cache due to a NPE:
