             Summary: Java 9: rework "sun.misc.SharedSecrets" and "sun.misc.JavaNioAccess" usages
                 Key: IGNITE-7352
                 URL: https://issues.apache.org/jira/browse/IGNITE-7352
             Project: Ignite
          Issue Type: Task
          Components: general
            Reporter: Vladimir Ozerov
             Fix For: 2.4


*Problem*
We have two usages of {{sun.misc.SharedSecrets}} and {{sun.misc.JavaNioAccess}} in the project. Both methods do the same thing - convert native pointer to {{ByteBuffer}}:
{{GridUnsafe.wrapPointer}} 
{{PageMemoryImpl.wrapPointer}}

Java9 cannot compile it because these classes were moved to {{jdk.internal.misc}} package.

*Suggested fix*
1) Remove {{PageMemoryImpl.wrapPointer}} method and use {{GridUnsafe.wrapPointer}} instead.
2) Rework {{GridUnsafe.wrapPointer}} to reflection-based approach.
