- Fixed returning null value type (parse1.cpp) That one confuses me. When does a return of a value type return something other than a ValueTypeNode? Is it with a method that returns the null constant?
Yes, it's with a constant null return. For example, if getNull (line 430) is compiled: http://cr.openjdk.java.net/~thartmann/valhalla/lworld_arrays/webrev.00/test/hotspot/jtreg/compiler/valhalla/valuetypes/TestLWorld.java.html
Thanks, Tobias
