Description
JCK            : JCK-runtime-6a b14
J2SE           : FAIL - jdk 7 b14, PASS jdk6u2 b05 JDK 7 b13
Platform[s]    : FAIL - seems to be all
switch/Mode    : FAIL - default

Tests 
api/java_awt/Color/index.html#CreateContextTesttestCase4[testCase4]
api/java_awt/Color/index.html#CreateContextTesttestCase5[testCase5]
api/java_awt/Color/index.html#CreateContextTesttestCase6[testCase6]
api/java_awt/Color/index.html#CreateContextTesttestCase7[testCase7]

fail since jdk 7 b14. Tests verify statement
"The same PaintContext is returned, regardless of whether or not r, r2d, xform, or hints are null." of java.awt.Color.createContext method.
Unfortunately, since b14 it returns different context.

Evaluation
The PaintContext class does not define a contract for the equals method
so the default contract of the equals method on a class implementing that
interface is the same contract as Object.equals().

Unfortunately, the createContext method on Color specifies that the same
Context is returned for each call to it.  This statement is unnecessary and
requires caching the return value to maintain that contract which is a
performance hit.  The same sentence also mentions that the return value
does not depend on various parameters being null or non-null and that part
continues to be true, that part of the sentence should probably remain,
though it should be considered whether or not the Paint interface requires
such conditions to be specified or not.

This doc statement should have been modified from the API description when
the code to cache the context was removed during the fix of 6530420.  I am
reassigning to AWT and the engineer responsible for that fix to complete
the appropriate modified Change Requests to modify the documentation as
per the fix of that bug.
