libjvm is the only non-system library used by test. So map layout will
look like (see map.1 attached):
<system library and its dependency from cache>
<all dependency for libjvm.so>
<libjvm.so>
[stack]
[vdso]
[vsyscall]
However, if we turn off cache for some reason (see map.2 attached) - you
are correct, we can't guarantee any particular place for libjvm.so.
