627 // Rationale behind JVM_FindClassFromBootLoader
628 // a> JVM_FindClassFromClassLoader was never exported in the export tables.
629 // b> because of (a) java.dll has a direct dependecy on the unexported
630 // private symbol "_JVM_FindClassFromClassLoader@20".
631 // c> the launcher cannot use the private symbol as it dynamically opens
632 // the entry point, so if something changes, the launcher will fail
633 // unexpectedly at runtime, it is safest for the launcher to dlopen a
634 // stable exported interface.
635 // d> re-exporting JVM_FindClassFromClassLoader as public, will cause its
636 // signature to change from _JVM_FindClassFromClassLoader@20 to
637 // JVM_FindClassFromClassLoader and will not be backward compatible
638 // with older JDKs.
639 // Thus a public/stable exported entry point is the right solution,
640 // public here means public in linker semantics, and is exported only
641 // to the JDK, and is not intended to be a public API.
