title: max size of java.nio.MappedByteBuffer
body: <p>I just want to make sure the max size of MappedByteBuffer is Integer.MAX_VALUE and there is no way to create a buffer of size 0x80000000. Although the index within this range can be represented by a value of "int" type, this size is not allowed by the specification of "java.nio", right? Thanks!</p>
