MH returned for a typed array by compiled MethodHandleImpl::varargsArray throws java.lang.ClassCastException: Cannot cast [Ljava.lang.Object; to [L<your fancy type>.
Issue could be reproduced by following tests starting from 8u40-b06:
java/lang/invoke/JavaDocExamplesTest.java
java/lang/invoke/VarargsArrayTest.java
With 8u40-b05 JavaDocExamplesTest pass, so it seems to be a regression.
This test also passes with 8u20-fcs and with 9-b31.
When MethodHandleImpl::varargsArray compilation disabled via -XX:CompileCommand=exclude,java/lang/invoke/MethodHandleImpl.varargsArray both tests pass.
