      Description

      The test java/nio/channels/FileChannel/ExpandingMap.java failed contantly with java.lang.InternalError: a fault occurred in a recent unsafe memory access operation in compiled Java code.

      I reproduced the issue manually and tried with different combinations of JVM options (-Xcomp/-Xmixed and -server/-client). However in all cases I got the same fault as one followed below:
