        MappedMemoryUtils.c can generate exceptions like those :
        java.io.UncheckedIOException: java.io.IOException: Invalid argument
               at java.base/java.nio.MappedMemoryUtils.force(MappedMemoryUtils.java:105)
               at java.base/java.nio.Buffer$2.force(Buffer.java:890)
               at java.base/jdk.internal.misc.ScopedMemoryAccess.forceInternal(ScopedMemoryAccess.java:317)
               at java.base/jdk.internal.misc.ScopedMemoryAccess.force(ScopedMemoryAccess.java:305)
               at java.base/jdk.internal.foreign.MappedMemorySegmentImpl.force(MappedMemorySegmentImpl.java:92)
               at TestByteBuffer.testMappedSegmentAsByteBuffer(TestByteBuffer.java:327)

        (we see this for example on AIX); there is some room for improvement, at least the info should be added that msync failed and caused this exception.
