Dmitriy Pavlov commented on IGNITE-5741:


I've checked by JDK 1.8.0_131, seems now it is possible to use more than 
64Mbytes. And also there is property to handle this limitation, see 
https://bugs.openjdk.java.net/browse/JDK-8147468

But still, if direct buffer is passed then it is used for read operation.
