RFR (T) 8232120: com/sun/jdi/InvokeTest fails with -Xcheck:jni: assert(k->is_instance_klass()) failed: cast to InstanceKlass

[coleen.phillimore at oracle.com]

Summary: Should have allowed recv klass to be an array.

Tested with tier1 -Xcheck:jni, all pass now.  There's another RFE to add 
-Xcheck:jni to our tiered testing.
