Thanks, I missed that.

Problem 3 disappeared but the ValueTypeTestBench still fails on Windows in test54_verifier and on my machine with -Xcomp:

#  Internal Error (/oracle/valhalla/hotspot/src/share/vm/opto/callnode.cpp:939), pid=10974, tid=10991
#  assert(false) failed: unexpected projection from allocation node.
