I was wondering that. It's fine to separate it from this bug.

classLoader.cpp - there are references to rt.jar that I think should be 
updated.

321   // Check whether zip name ends in "rt.jar"
1322   // This will match other archives named rt.jar as well, but this is
1323   // only used for debugging.
1324   return string_ends_with(zip->name, "rt.jar");

1352     // We stop at rt.jar, unless it is the first bootstrap path entry
1353     if (e->is_jrt() && e != _first_entry) break;

Found rt.jar in comments - probably to take out those.

src/share/vm/opto/library_call.cpp:
2601:  // of safe & unsafe memory.  Otherwise fails in a CTW of rt.jar

src/share/vm/opto/type.cpp:
3125:    // Happens in a CTW of rt.jar, 320-341, no extra flags
