The new assertion in src/hotspot/share/utilities/globalDefinitions.hpp

inline const char* type2name(BasicType t) {
  assert((uint)t < T_CONFLICT + 1, "invalid type");
  return type2name_tab[t];
}

is failing with test

compiler/jvmci/errors/TestInvalidDebugInfo.java

I have filed:

https://bugs.openjdk.java.net/browse/JDK-8287491

The test will probably need ProblemListing as it is causing major noise in our CI.

As you can see, the warnings spreads several areas. Let me know if I should 
separate them by area.
