Java 1.8.0_131 + Windows Server 2012 R2.
'-Xmx=9000m'. But Windows Task Manager shows the java process uses more than 14 GB memory.
NMT shows "Internal" consumes more than 4.5 GB memory. Why does this occur? I understand it is not Java functionality to define spaces for the native memory. But is there any method to limit the 'Internal' memory?
