There is a problem in the logic of SystemDictionary::find_method_handle_invoke when the classes of the signature are not on the bootclasspath. In that case the method returns always the newly created method resulting in the assert above.
Putting the classes on the bootclasspath makes the testcase work up to a point where it hits another assert:
# To suppress the following error report, specify this argument
# after -XX: or in .hotspotrc: SuppressErrorAt=/sharedRuntime.cpp:2693
==============================================================================
Unexpected Error
------------------------------------------------------------------------------
Internal Error at sharedRuntime.cpp:2693, pid=23705, tid=68
assert(fr.interpreter_frame_expression_stack_size()==0) failed: only handle empty stacks
Do you want to debug the problem?
To debug, run 'dbx - 23705'; then switch to thread 68
Enter 'yes' to launch dbx automatically (PATH must include dbx)
Otherwise, press RETURN to abort...

It seems we have a race here we have to take care about.
