Current test in lworld fails reliably:

$ make test TEST=java/lang/invoke/VarHandles/VarHandleTestMethodHandleAccessValue.java

...

# Internal Error (/home/shade/trunks/shipilev-valhalla/src/hotspot/share/opto/escape.cpp:1580), pid=384613, tid=385114
# assert((ptnode_adr(adr->_idx) == nullptr || ptnode_adr(adr->_idx)->as_Field()->is_oop())) failed: sanity

# Problematic frame:
# V [libjvm.so+0xe2e3a0] ConnectionGraph::add_objload_to_connection_graph(Node*, Unique_Node_List*)+0x140


Node dumps say there is AddP -> LoadN chain here, and is_oop_field on AddP returns false.

The symptoms look similar to JDK-8250951 and JDK-8281454.
