[jira] [Commented] (MNEMONIC-299) implement Java based memory allocator

    [ https://issues.apache.org/jira/browse/MNEMONIC-299?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16120840#comment-16120840 ] 

Peili SHEN commented on MNEMONIC-299:
-------------------------------------

met the issue on createByteBuffer().  the returned addresses are not continuous addresses for the continuous createByteBuffer() as below, so as Gang's guided, I will try another solution.

ByteBuffer buf1 = fc.map(MAP_MODE, 0L, 1024);
System.err.print(getByteBufferHandler(ret, buf1));  //140431399190528⁠⁠⁠⁠
ByteBuffer buf2 = fc.map(MAP_MODE, 1024, 1024 * 10 * 1024 - 1024);
System.err.print(getByteBufferHandler(ret, buf2)); //140430790362112
