    -XX:+PageAlignDirectMemory option

    818d78e2-767b-4e0a-b074-05127d3b8c4f

      According to Java SE 7 Features and Enhancements you can add the "-XX:+PageAlignDirectMemory" option to the java command line to force directly-allocated ByteBuffers to be page aligned.

       

      When I try and use the option, however, I get an error: Unrecognized VM option 'PageAlignDirectMemory'

      This is using JDK version 1.7.0_25 on 64-bit Linux.

       

      Anyone else get the same problem?
