-// b> because of (a) java.dll has a direct dependecy on the  unexported

-// c> the launcher cannot use the private symbol as it dynamically opens

-//    unexpectedly at runtime, it is safest for the launcher to dlopen a

-// d> re-exporting JVM_FindClassFromClassLoader as public, will cause its
-//    signature to change from _JVM_FindClassFromClassLoader@20 to
-//    JVM_FindClassFromClassLoader and will not be backward compatible
-//    with older JDKs.
-// Thus a public/stable exported entry point is the right solution,
-// public here means public in linker semantics, and is exported only
