Description
When all core classes have been had the null retransformation applied to them the following assertion fails.

Currently tested only in client compiler in a debug build.  Only happens sporatically unless -Xcomp is used, in which case failure is regular.

---------------------------------------------------------

Dependency method not found in the associated context:
  context = java.io.BufferedWriter
  method =  java.io.Writer::write
  found =  java.io.Writer::write
# To suppress the following error report, specify this argument
# after -XX: or in .hotspotrc:  SuppressErrorAt=/dependencies.cpp:1150]

# An unexpected error has been detected by Java Runtime Environment:

EVALUATION Fixed as part of 6404550, closing as a dup of that.

SUGGESTED FIX Restore the is_old flag on methods so that compilation and some other operations will be avoided on old methods.

EVALUATION This problem is caused because the compiler (and, it would appear, other parts of HotSpot) expect that a method will be a member of its class. This failure is a problem in its own right and is also a blocker for addressing other redefine/retransform issues.
