As you can see from the below log:
* actual lock acquisition timeout in lockAndRecord is 10 seconds which equals to timeout on the cache level. (time between MVCCLockManager.lockAndRecord and MVCCLockingInterceptor.doAfterCall). 
* the value of InvocationContext.getLockAcquisitionTimeout is 0. (exception message "... Unable to acquire lock on Fqn [...] after [0] milliseconds ..." produced by MVCCNodeHelper.acquireLock)

In particular this affects behaviour of Cache.putFromExternalRead
