JSR292: IncompatibleClassChangeError in LambdaForm for CharSequence.toString() method handle type converter

Compilation of LambdaForm CharSequence.toString() MH type converter produces incorrect bytecode.

Exception in thread "main" java.lang.IncompatibleClassChangeError: Found interface java.lang.CharSequence, but class was expected
at java.lang.invoke.LambdaForm$MH/707806938.convert(LambdaForm$MH:1000001)
at java.lang.invoke.LambdaForm$MH/317983781.invokeExact_MT(LambdaForm$MH:1000010)
at TestCharSequence.main(TestCharSequence.java:13)

  static java.lang.Object convert(java.lang.Object, java.lang.Object);
    flags: ACC_STATIC
    Code:
      stack=1, locals=2, args_size=2
         0: aload_1
         1: invokevirtual #16 // InterfaceMethod java/lang/CharSequence.toString:()Ljava/lang/String;
         4: areturn

CharSequence is an interface, so invokevirtual fails to invoke toString method and throws ICCE.

The test case passes fine in jdk7.

Filed against hotspot/compiler (and not core-libs/java.lang.invoke), because initial analysis shows that VM returns wrong info when resolving corresponding MemberName:
jdk/src/share/classes/java/lang/invoke/MemberName.java:965
                m = MethodHandleNatives.resolve(m, lookupClass);

before: m = java.lang.CharSequence.toString()String/invokeInterface
after: m = java.lang.CharSequence.toString()String/invokeVirtual

ILW = HLH = P2
I = H = regression against jdk7
L = L = very unlikely: (1) interface on boot class path; (2) overrides a method from Object; (3) MH type is converted; (4) MH invoked enough to be compiled into bytecode
W = H = none
