MethodHandles.catchException() fails when methods have 8 args + varargs

FULL PRODUCT VERSION :
java version " 1.7.0_40-ea "
Java(TM) SE Runtime Environment (build 1.7.0_40-ea-b29)
Java HotSpot(TM) 64-Bit Server VM (build 24.0-b48, mixed mode)


ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 6.1.7600]

EXTRA RELEVANT SYSTEM CONFIGURATION :
64 bit OS and VM.

A DESCRIPTION OF THE PROBLEM :
When binding an exception handler for a method using java.lang.invoke.MethodHandles.catchException() the binding will fail if the target has eight arguments plus a trailing vararg Object[] argument. Smaller numbers of arguments before the varargs work.

REGRESSION. Last worked in version 7u25

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Build attached test case. Run it, and observe the output.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
java -classpath . MethodHandleBug
Java Version is 1.7.0_25.

Working case (8 args).

Handler is a MethodHandle(Exception)Object.
Body8 is a MethodHandle(Object,Object,Object,Object,Object,Object,Object,Object[])Object.
Prim8 is a MethodHandle(Object,Object,Object,Object,Object,Object,Object,Object[])Object.
Prim8 with Handler is a MethodHandle(Object,Object,Object,Object,Object,Object,Object,Object[])Object.
Body8 with exception is a MethodHandle(Exception,Object,Object,Object,Object,Object,Object,Object,Object[])Object.
Prim8 with fallback to body8 is a MethodHandle(Object,Object,Object,Object,Object,Object,Object,Object[])Object.

Failing case (9 args).

Handler is a MethodHandle(Exception)Object.
Body9 is a MethodHandle(Object,Object,Object,Object,Object,Object,Object,Object,Object[])Object.
Prim9 is a MethodHandle(Object,Object,Object,Object,Object,Object,Object,Object,Object[])Object.
Prim9 with Handler is a MethodHandle(Object,Object,Object,Object,Object,Object,Object,Object,Object[])Object.
Body9 with exception is a MethodHandle(Exception,Object,Object,Object,Object,Object,Object,Object,Object,Object[])Object.
Prim9 with fallback to body9 is a MethodHandle(Object,Object,Object,Object,Object,Object,Object,Object,Object[])Object.

CUSTOMER SUBMITTED WORKAROUND :
We have changed our source to work round this problem by gathering more args as varargs, but the same problem could crop up in other areas we have not yet tested.
