+Still there is an option for using fields beyond the actuall
+object that could produce unexpected behaviour.
+Array access in the MJVM does check for indexe out of bounds
+errors.
+
+The size of the heap is not taken into consideration when
+allocating new arrays and objects. What this means is that
+there will be no heap overflow exception thrown, since our
+heap is seemingly endless.
+
+Null access does not throw explicit errors, although it
+will cause problems with the list access.
